Designing a 3 - 4 GHz pre-amp using my own software. Something I never mentioned in the video is that the components do not need to be connected with wires, but need to be placed in order as I show in my software. Also all the vertical components are automatically grounded, no need to ground them. If you like the software enough, I would be pleased to give a copy, but with gratitude.

Comparing my S-parameter magnitude/gain graph I designed in C and compared the graphs to ADS and MATLAB. The corrected version of the graph is in the thumbnail! not sure how I can edit the video to correct the graph. Had some formulas wrong in the program!

Going from PCB layout (LNA) to Manufacturing using ADS and Eagle
Переглядів 1,4 тис.4 роки тому
In this video I will mostly show how to generate the files needed by your PCB manufacture (Im using PCBWay) using ADS and Eagle. These files contain outline layer (substrate), drill files (vias), top (conductor), and bottom layer (conductor). I also show my design methods and simulations to my 2.4 GHz LNA design, which is what I am getting manufactured. I will show the test results to my LNA de...
How to design a 3 GHz LNA on ADS layout (2 of 2)
Переглядів 9 тис.5 років тому
In this second video, I design the 3 GHz LNA on a PCB layout, then transfer the layout to the schematic to generate an s-parameter plot. BTW you do not need to use gnd! to setup a ground. All I should have done is put grounds on the bottom plane for the completed circuit. I do have a picture of the actual ADS model for ATF55143 on my Patreon web site: www.patreon.com/ChrisVsRFelectronics, you c...

2.4 GHz microwave amplifier
Переглядів 1,1 тис.6 років тому
using my MATLAB program to design 2.4 GHz microwave amplifier. This is more ideal and does not include parasitics in devices. If you want more accurate results, work with ADS software instead! This shows you the math behind building these microwave amplifiers.

This is awesome!!!
Agreed.
Thanks you hommie!
I really need your help brother! Can you share me your mail or something to contact you please. I have to implement a microwave amplifier in 4.5Ghz. If you can help me please
I will soon make my software work, so that you will be able to amplify in steps of 100 MHz, Will get this working soon and you can use it to design your 4.5 GHz amplifier!
Good to see Crish
👍🏼Thanks!
Very helpful.
Glad to see this new information. Really interesting! Thanks Chris!
Thanks for sharing your info!
Thank you! So glad your videos are still here.
Hello Chris, can you please share the ADS model of ATF-55143 ? the link to your giyhub isn't exist anymore...
Hi, sorry it was on private, I just made it public. You can view it now, it should be the file that says: ATF55143 . dds. Let me know if you got it! Thanks
@@chrisv1459 yes, thank you. i'm not familiar with dds file so i'm trying to learn how to use it...
hey so i did all of the things, the only thing that it transferred was the blank brand account, not the one with the videos on it. What did you do?
You can either go back to 6:12, or as I showed, I created a brand account, after that, go to settings inside brand account, then click on Add and manage your channel, then click on your new account name (not brand account), then go to settings again and then you should see add or remove managers and click on that and then just keep following the video after that. Hope this helps, let me know if you run into problems with what I wrote, thanks.

Hi Chris, can you share the model ATF-55413 model to me please? Because I can't find it on Broadcom website. Thank you!
Hey Chris. I'm trying to do exactly what you did in this video but I'm running into a bit of confusing information. Would you mind helping me out? I'll give you my contact info and happily pay you to talk me through the process. Thanks a lot! This gives me hope.
Hi @retroland6007, you can shoot me an email at 1989coolkid9891@gmail.com, same email I used for a personal account I used in this video. Just provide a day and time you're available and we can try a screen share?
Hi, I was in the same situation as you (albeit a teacher) and this was very helpful. Thanks!
not available now mate, could you share it
could you please explain why do we need a dc feed inductor at the output of the transistor please , what is the exact role of this inductor since it is conected to the power suply , thanks ...
The inductor helps provide biasing for the transistor and also blocks any of the RF signal from leaking into the DC power line.
For an LNA to be unconditionally stable, the stability circles must lie either totally enclose or totally outside the smith chart. Refer: Pozar, David M. Microwave Engineering, Pg. 566 Edit: Given, |S11|<1 and |S22|<1
Thanks Sir for great video. As I designed my circuit, I realized that the EM performance was affected by location of "Ground port" that was put on the ground plane. Can you explain about that performance change and recommend its optimal position.
Hello cris ,do you still have the design document?
What different between 2.4GHz and 3GHz
thank you for the tutorial. very helpful
Liking your vedios and way if designing the products.have seen ur LNA design . if u have given voice over to this vedio it used to be good😊☺
How we can download the text u have shown pls give us the pdf
you are a life saver, my graduation project depended on designing using ADS and when it came to fabrication we were lost and thought that we are going to fail. Thank you very much sir.
Outstanding job.
Please share your ppt
How can I find the data for lower frequencies on de datasheet for the Nf, Gain, Sparam, etc?
@@chrisv1459 Ok. I manually tested but not sure, I'm working in 128MHz and using ATF34143... One thing that I am in trouble with is that after getting in matlab, my input impedance is very high (3.5498e+02 - 3.0046e+02i) and the output is ok (60.6123 -20.8016i). Second, I am not sure that the noise and gain circles it is ok (it seem that they are coming from the Right side of the smith chart with the near edges). My GaCircle block is "GaCircle1=ga_circle(S,{19,20,21,22,23,24.3},51)" and my NSCircle is NsCircle1=ns_circle({0.05,0.09,0.21,0.58,1.04},0.013,0.98+j*0.03,4.32/50,51)". My final concerning is that my S11 is horrible (near 0dB) even with the shunt resistor. My circuit is stable and I'm not sure if I design the L-C matching circuit (not the transmission line or stub) can solve this s11 problem...

i honestly cant thank you enough for your LNA design tutorial on this channel..it helped me pass my pratical :) thankyou sooo much
hello fellow engineer :)
very nice. great job. glad to see we have true radio experimenters on youtube
Exactly what I need. Very helpful, thanks a lot!
Hi.I interested about rf signal products.My work is about rf signals.My company have ideas about rf products.Your videos and your information good in that matter.ıf you can help me we can discuss about us project and we can work together.

Good going friend
Nice videos. I’ve been following your videos. Would like to ask, if possible to do a video on power amplifier. Anyways a big thanks for uploading this video. 🙏Appreciate your good work.
Can you give me s2p file? Thank you so much anhnguyen29798@gmail.com
It is a great video dude, but you are not designing an LNA.
In the Derivation of the K factor there is an condition for the S Parameters (|s12|*|s21|)/(1-|s22|²)<1 that has to be fulfilled. Only if that condition is fulfilled and K is greater one, then the circuit is stable. edit: The mu factor takes this extra condition into account.
can you help to some problem in my project , please chris
Good tutorial. Very very helpful. Could you please give us the title of the book you used in your first video?
Thank you so much, Chris, this video helped me a lot in learning how to design LNA. Great lecture
bro can you please let me how to import that symbol in another schematic
I get "gamma2z" undefined, any help plz
Please tell me how to load this exemple under ADS? i copy it in the library?
Hi Chris. Could you share the title of your book?
This is very helpful. Thank you for sharing your knowledge. This helped me do finish project.
