How do I feed one antenna with tow different high power rf amplifier?one at 900Mhz another at 2100Mhz?
feeding one antenna with two different signal at different frequency without loosing too much power,currently I am using a high power combiner to combine this two signal(50 watt each one),but I lost half of this power in splitter,is there any other way to combine two or three signal(different in frequency and Power Level) and feed one antenna with that?
Thanks in adavance
What you are asking for is a specially designed filter which will combine 2 widely different frequencies with very little loss. I tried searching for this item but could not find it, probably because I don’t know the proper name for this item.
I know about this technique from lower frequency methods (audio).

I think what you are looking for is a diplexor. This one looks like it should work.
