Great video! I just had an exam where loss and resistance of a resistive splitter was two of the questions, and it seems i answered it correctly according to what you shared in this video. Now im pretty sure I passed the exam before getting the grade.. Thank you very much!
I have made those with 18R resistors, and they work well enough for most applications. Made plenty to do network splitters when I had no spare ports on the hub ( yes hub not switch with coax cabling) and the cables involved were short. Even did a few to combine and split TV and FM signals down the same coax, and I was too cheap to buy the ferrite ones. Plenty of signal at the antenna as I could see the transmitter with 20kW of output 12km away, but I was down in a RF hole. Even worked when the antenna rotted off and left only the dipole on the pole.
Nice video. Great for mixing 2 Tones from the cheaper Feeltech 6800/6900 for SSB LINEARITY on cb radios as they do not have mixing stagein the sig gen.
Dear Sebastian, thanks for sharing this very usefull video. I wonder its DC characteristic as well. You hooked AC signal into the splitter from Signal Generator and then check the signal level in the ossiloscope. Does the part exhibit similar figures when you apply DC offset or only DC voltage ?
The thing I don't understand is how resistive splitter provide isolation between two inputs ? Also how the delta loss is -6dB I don't understand the current flow there
The star splitter doesn't seem like it would total 50ohms.. Two parallel resistors are in series with a single resistor... Seems it would be 16.6 + 16.6/2... Total about 25 ohms... Hmmm. I'm missing something....
Sigh aren't you're an American!? No need to hate on the way we do things! Hey the squiggly resistor is so much easier/quicker than having to make a box. But the video was awesome. Great work.
Haha, if you can't tell the difference between an American resistor, and a ... erm ... rest of the world resistor than you have no business making a combiner XD but yeah i am an american and i use the boxes over the squiggle, i like it better But i do use the american symbol for polarized caps

Makes a fuss about American resistor symbol... back to the program and "ZEE"!!
Great video, thanks :D

This is really helpful.

Great video. But what if the two input signals have the same frequency when it is used as a combiner?

Good videos !

THANKS

Negative, not American. I live here but I am not an American citizen (yet).
I still consider you an American if you live here haha
Wait there are non-american countries?! DX
