@@HansRosenberg74 I posted this video to the amateur radio subreddit... the fact that your examples are RF filters puts it right up our community's alley. I don't know how much you intend to cover RF, but it's not easy to find good material in this area!
I get it, RF seems to be a 'desert' on the internet. I think it would be a good idea for my channel to cover more, people seem to really like it :-) My main focus is audio actually, but I design my audio devices like RF devices since they're sensitive to all RF radiation out there (am demodulation which causes Transient Intermodulation Distortion). I do plan to show how to make a simple RF amplifier board. Seeing the enthusiasm, maybe I should to more.
Thank you. Strangely, after a lifetime in electronics, this is the only presentation on this topic I've seen with such clarity! Would very much appreciate the check list.
Thanks for the link to the checklist in the video description! One of the best video series I have found on YT in a while. Excellent explanation. That was a lot of hard work to put together so succinctly. And maybe I am slightly biased towards your nice accent. 😆 Watched too much @itchyboots .
Beautiful. I have worked with grounding strategies well, but not in RF. In the Audio range, we created attenuators with up to 165dB of dynamic range and a preamplifier with 180dB of CMRR under ideal conditions. We moved grounding points just tenths of an mm and sometimes had to go off the board with twisted pair conductors. I would love to have the time and capability to make a video like yours on this subject!
Wow, did you really achieve 180dB? Are you really sure, I don't know of any analyzer yet with that kind of dynamic range to measure this. I can imagine a tenth of a mm will make a huge difference, you're talking a factor of 1.000.000.000 between the largest and smallest signal! I would be really really curious to see a video on that project as well, sounds really impressive. You have the same kind of mm problem when taking the feedback point of a power amplifier, if you put that a little off center, the distortion will get larger since you have currents coming from the top half and the bottom half of the output stage.
@@HansRosenberg74 yes, achieved this - the measurements made by one of my colleagues who is an analogue wizard, using crazy step-up and attenuation chains, the instrument was R&S UPV150 - you need to know what you are doing, promise…… Such fun times

Hi, thank you for great tips and explanation! I want to suggest a topic: impedance stub matching. Very important and interesting topic. If possible, mention the difference methods/materials when increasing the frequency.
Unfortunately, I've never done that and the information on the internet is not great. I did do some impedance matching using non 50 Ohm lines, it is a part of the stub matching procedure and relatively easy to design. I will do a video on that in the future.

I'm probably confusing now :-) ). Maybe it is something you can use (if your boss is willing to pay for it :-) ). Best regards, Hans
Very nice introduction to the subject. What a lot of people miss is that while the signals they are dealing with may be below 100MHz, where a substandard layout may "work", it makes it susceptible to picking up interference at much higher frequencies. These are often handled by the circuitry in a non-linear way, creating frequencies within the bandwidth of the signals of interest. As we live in an age of GHz radio links and high-speed digital everywhere, even audio and DC circuitry can benefit from following good high frequency PCB layout techniques. Please send me the checklist!
You're absolutely right. You're one of the few electronics engineers who realizes this. It's a really big problem. Audio sounds a lot worse if you don't design to prevent this sort of thing. I've got a solution for that and I'm going to make a video on the subject somewhere in the coming year. Many electronic equipment needs to pass audio breakthrough tests, you only achieve that with good grounding and good Common Mode filtering.

I get that, I'm basically a free lancer as well :-) And indeed, I am thinking of cutting it up into smaller parts, but I first need to get the whole thing I think, and sell a few so I can get through the next year :-)
Great video. One thing I have noticed when dealing with HF filter boards is a bit of symmetry on both sides. Many of the HF 2 layer boards I have seem to have some symmetry on both sides. They have the same amount of copper on each side of the board for ground planes. I think this helps with stray capacitance or inductance. If they do something with one side, they do the same on the opposite side when looking down the length of the board. They also use the full solid ground planes on the bottom as well. And they seem to work well. Look forward for the next video
I think the frequency of this is still too low to be really impacted by symmetry, the wavelength at 1GHz is still quite long and the components have so many parasitics there already that those dominate the performance when using a 4 layer pcb.
I think the symmetry has more to do with some PCB manufacturing processes - depending on the process it can be more difficult for the manufacturer to electroplate the same thickness of copper onto both sides, or etch for the same time without different amounts of undercut, if there is vastly different copper areas on the two sides. More recently I have not seen rules about this, so perhaps changes in manufacturing mean that PCB manufacturers no longer have difficulty with this. In any case with symmetrical copper coverage there is less tendency of the board to bend when it is heated or cooled due to the different thermal expansion coefficient of copper and FR4.
Thanks a lot. Electronics is not that hard if you really understand it fundamentally, I hope to show that in my channel :-) Link is in the description. Best regards, Hans
Excellent video. In my early engineering days, I worked extensively to dedi e ground plane design rules, including such matters as ground plane capacitance effect on the sizing of power decoupling caoaciorsr
This was great.. thank you! I'm looking forward to the 2 layer board video, as I'm making prototype boards at home that I'm sure will benefit from your best practices.
Thanks for the encouragement! I'll be working on this video the coming week. I'm not 100% sure what gains I am going to make, I'll start measuring today.
I have spent many years learning all this from various IC manufacturer datasheets and application notes. Thank you for sharing this valuable knowledge. Would appreciate getting your checklist.
@@HansRosenberg74 Thank you! The boards arrived yesterday and against all odds they actually work. I haven't field tested them yet so I can't tell how they perform in more demanding situations, but they accurately send my location and infos from quite a few satellites when placed on my terrace.
This is a great tutorial thanks a lot. but i miss one tip they learnd me making proper grounding for RF. To use more than one ground via on the path to ground. They act as coils in parallel decresing the inductance even more.
Really clear explanation of ground loops- thank you! As a pragmatist I appreciate the comparison of the theoretical data and actual responses. I’d like to get a copy of the guidebook that you offered please!
Link is in the description! Solving hum can be a bit nasty sometimes. You may have a loop at the input of your valve amp which is picking up an electromagnetic field from a transformer. You may also lack enough decoupling caps on your main supply and a limited power supply rejection ratio somewhere. Sometimes the ground impedance is too high and you have a ground current running through there between 2 mains transformers. So, can be tricky to find the cause.....
Congrats for the very good explanations backed up by real measurements. Looking forward to your next videos! Spotted one error: in the via impedance measurements the inductance is presented to be in nH. 500nH is quite a lot. Must be pH as shown in the inductance graph.
Ah, darn, I missed another one? It is soo hard to get good personnel these days (even if that's me :-) ). I fixed it in one location with text on the screen, but I missed another one apparently. 500nH would be a really really long via :-) (or a really really thick board)
UA-cam is just amazing to learn anything. I wish I had that when I was a kid, then I would be a much better electronics engineer now. Internet started a little bit when I was 22 years old :-) Part three is coming within a day :-)
Agreed! I just always get scared by the 0.8mm boards since they're so flimsy, even small ones bend very easily and I worry about cracking smd components.
@@HansRosenberg74 I was just thinking about this when the board stackup graphic came up: Manufactures always have the 0.8mm core available as a 2-layer board option. But having the components flex off by accident would be a shame. Putting the design on Front and Inner Copper 1 in a 4-Layer PCB for the sexy 0.18 vias you mentioned is definitely the way to go then, thanks for your insight! I subscribed for part 3, knowing the limitations better would be helpful!
Hans, excellent presentation. Wish I had started electronics when I was a kid. 74rs old but still keen on learning would appreciate any help regarding pcb repair look forward to you book, many many thanks.
Thank you for putting this together! Very helpful to see how layout decisions affect performance. I asked for your book in a comment on your previous video, so I won't say "Send me the checklist" in this comment. :-)
Hi there, thanks for the positive review. You can get the checklist here: www.hans-rosenberg.com/checklist Let me know if it works, you're the first one to test this download on my new website :-). I'm new to all of this stuff, it's a little different from developing circuits and boards :-)
This is a really good video, learned a lot in 11 minutes. There are several good video's about digital design by Bogatin et all. But I really like the analog filter example. Thanks
Great to see the real life measurements to back up the theory!! Was going to ask if you tried multiple vias to lower the inductance even further, but looks like you tried that in part 3
Smashing stuff - and a super concise delivery, thank you! I have a similar experience to you (although not quite so old😅 yet). The jump to four layer boards with two inner ground planes makes a huge difference, I haven't failed at the EMC lab since I made it my default position a few years ago.
Excellent video! The filter was a great example subject! I always wondered why I never could get more than about 40db rejection in some of my filters! I was questioning if peppering the ground with vias makes any difference and will wait till your next video to get the answer! Do you have microwave instrumentation? I have had no significant problems until I went above about 400MHZ. The 2.5GHZ stuff is still magic to me. Be sure to cover the effects of pcb material!
Excellent video, in just a few minutes I've recalled some theory that was in the back of my mind and learned some new things. Would love some more of these in depth video's. So with this said, would you please send me the checklist. 73.
Very interesting ! Thank you ! I hope you will continue to make videos. What do you use for your measurements (spectrum analyser/software) ? "I will be posting a video in the future how to reflow SMD boards at home or in a small workshop with very cheap tools." I hope it will be soon 😁

I get that, I'm basically a free lancer as well :-) And indeed, I am thinking of cutting it up into smaller parts, but I first need to get the whole thing I think, and sell a few so I can get through the next year :-)
Thank you for sharing the checklist !
You're welcome
Really like the practical examples. Please also send med the checklist.
Thanks. Link is in the description. Best regards, Hans
Great video. One thing I have noticed when dealing with HF filter boards is a bit of symmetry on both sides. Many of the HF 2 layer boards I have seem to have some symmetry on both sides. They have the same amount of copper on each side of the board for ground planes. I think this helps with stray capacitance or inductance. If they do something with one side, they do the same on the opposite side when looking down the length of the board. They also use the full solid ground planes on the bottom as well. And they seem to work well. Look forward for the next video
I think the frequency of this is still too low to be really impacted by symmetry, the wavelength at 1GHz is still quite long and the components have so many parasitics there already that those dominate the performance when using a 4 layer pcb.
I think the symmetry has more to do with some PCB manufacturing processes - depending on the process it can be more difficult for the manufacturer to electroplate the same thickness of copper onto both sides, or etch for the same time without different amounts of undercut, if there is vastly different copper areas on the two sides. More recently I have not seen rules about this, so perhaps changes in manufacturing mean that PCB manufacturers no longer have difficulty with this. In any case with symmetrical copper coverage there is less tendency of the board to bend when it is heated or cooled due to the different thermal expansion coefficient of copper and FR4.
Yes please! Send me the checklist!! Great video!!
Please always works with me :-)

Thank you for this video
My pleasure
About to start my first higher frequency layout and was glad to find this clearly explained video. Please send me the Checklist.

What a beautiful step by step demostration of these concepts. I would like to have your checklist 👌
Thakns a lot Link is in the description. Best regards, Hans
Hi, nice to see good production quality videos and a simple explanation without needlessly overcomplicating! Could you please send me the checklist ?
Thanks a lot. Electronics is not that hard if you really understand it fundamentally, I hope to show that in my channel :-) Link is in the description. Best regards, Hans
Excellent video.
In my early engineering days, I worked extensively to dedi e ground plane design rules, including such matters as ground plane capacitance effect on the sizing of power decoupling caoaciorsr
thanks
This was great.. thank you! I'm looking forward to the 2 layer board video, as I'm making prototype boards at home that I'm sure will benefit from your best practices.
Thanks for the encouragement! I'll be working on this video the coming week. I'm not 100% sure what gains I am going to make, I'll start measuring today.
I have spent many years learning all this from various IC manufacturer datasheets and application notes. Thank you for sharing this valuable knowledge. Would appreciate getting your checklist.
Thanks a lot.

Thank you, clear concise explanation.
You're welcome
Great series of videos. It's a pity I discovered it two days after I ordered my second PCB ever... a 2-layer GPS receiver 😅
Ah darn, hope it still turns out well!
@@HansRosenberg74 Thank you! The boards arrived yesterday and against all odds they actually work. I haven't field tested them yet so I can't tell how they perform in more demanding situations, but they accurately send my location and infos from quite a few satellites when placed on my terrace.
Thanks very much for this video, it's very helpful! Please send me the checklist also! 🙂
Thanks! Link is in the description. Best Regards, Hans
This is a great tutorial thanks a lot. but i miss one tip they learnd me making proper grounding for RF. To use more than one ground via on the path to ground.
They act as coils in parallel decresing the inductance even more.
That is in the next video that's already published, see the description.
Really clear explanation of ground loops- thank you! As a pragmatist I appreciate the comparison of the theoretical data and actual responses. I’d like to get a copy of the guidebook that you offered please!
Please always works with me :-)

Very interesting video, I have a valve audio preamp with hum and would like your checklist to help solve that. Thanks Chris
Link is in the description! Solving hum can be a bit nasty sometimes. You may have a loop at the input of your valve amp which is picking up an electromagnetic field from a transformer. You may also lack enough decoupling caps on your main supply and a limited power supply rejection ratio somewhere. Sometimes the ground impedance is too high and you have a ground current running through there between 2 mains transformers. So, can be tricky to find the cause.....
Congrats for the very good explanations backed up by real measurements. Looking forward to your next videos!
Spotted one error: in the via impedance measurements the inductance is presented to be in nH. 500nH is quite a lot. Must be pH as shown in the inductance graph.
Ah, darn, I missed another one? It is soo hard to get good personnel these days (even if that's me :-) ). I fixed it in one location with text on the screen, but I missed another one apparently. 500nH would be a really really long via :-) (or a really really thick board)
Very good video, concise, useful, well made, and well analysed. Thank you!
thanks!
Send me the checklist! Thanks for the video series!

I'm really looking forward to part 3!
Great info for a hobbyist just learning KiCad.
Amazing things we can do from the couch these days!
UA-cam is just amazing to learn anything. I wish I had that when I was a kid, then I would be a much better electronics engineer now. Internet started a little bit when I was 22 years old :-) Part three is coming within a day :-)
you can also get close planes and short vias on two layer boards by just using a thinner pcb options (if possible of course)
Agreed! I just always get scared by the 0.8mm boards since they're so flimsy, even small ones bend very easily and I worry about cracking smd components.
@@HansRosenberg74 I was just thinking about this when the board stackup graphic came up: Manufactures always have the 0.8mm core available as a 2-layer board option.
But having the components flex off by accident would be a shame. Putting the design on Front and Inner Copper 1 in a 4-Layer PCB for the sexy 0.18 vias you mentioned is definitely the way to go then, thanks for your insight!
I subscribed for part 3, knowing the limitations better would be helpful!
pcbway 4 layers have 0.19mm as standard :-) not very expensive
Excellent videos Hans, exactly what's needed, simple to remember rules with evidence to back them up. Please send me your checklist.

Let me know if it works, you're the first one to test this download on my new website :-). I'm new to all of this stuff, it's a little different from developing circuits and boards :-)
@@HansRosenberg74 I've downloaded it successfully from your website! - looks good
This is a really good video, learned a lot in 11 minutes. There are several good video's about digital design by Bogatin et all. But I really like the analog filter example. Thanks

Great to see the real life measurements to back up the theory!! Was going to ask if you tried multiple vias to lower the inductance even further, but looks like you tried that in part 3
I was anticipating your question, I'm also trained in telepathy :-)
Smashing stuff - and a super concise delivery, thank you! I have a similar experience to you (although not quite so old😅 yet). The jump to four layer boards with two inner ground planes makes a huge difference, I haven't failed at the EMC lab since I made it my default position a few years ago.
Yes, it makes a huge difference. And saves loads of time and PCB spins :-)
Send me the check list, please.

Hi Hans, I would appreciate it if you could send me the document. Glad to see your new channel sharing years of experience

Excellent video! The filter was a great example subject! I always wondered why I never could get more than about 40db rejection in some of my filters! I was questioning if peppering the ground with vias makes any difference and will wait till your next video to get the answer! Do you have microwave instrumentation? I have had no significant problems until I went above about 400MHZ. The 2.5GHZ stuff is still magic to me. Be sure to cover the effects of pcb material!
Thanks for the nice comments! I'll do my best to explain as much as possible in the next video.
Just starting out into RF electronics and microcontrollers. Id love for you to please send me the checklist for design!

Very interesting ! Thank you ! I hope you will continue to make videos.
What do you use for your measurements (spectrum analyser/software) ?
"I will be posting a video in the future how to reflow SMD boards at home or in a small workshop with very cheap tools."
I hope it will be soon 😁
I've got so much material I don't know where to start. And, I 'have' to go on vacation for 3 weeks :-)
I use a nanovna with python code to read it
