How to feed an antenna with two different RF power amplifier? One other on 2100Mhz to 900Mhz?
feeding an antenna with two signals different in different frequency, without losing too much power, now I'm using a high power combiner for combining the two signals (50 watts each), but I lost half of this power splitter, is there another way to combine two or three signals (different frequency and power level) to feed an antenna with that? Thanks in Advance
What we are asking for is a special designed filters that combine 2 frequencies very different with very little loss. I tried searching this issue but could not find it, probably because I do not know the correct name of the item. I know about this technique of lower-frequency methods (audio). Here is http://www.smelectronics.us/SF2710.pdf I think you are looking for a diplexer. It seems it should work.
