Hi.I have designed an LNA for S-band between 2.2-2.4 GHz bands. The thing is when i test it i see this weird stuff on Spectrum analyzer like some 50 MHz signal is getting mixed in.I couldnt really work out a reason. can you give me a clue why it might be doing this ? You can see my marker is at 2.2 GHz but it doesn't give the wanted amplification. If it worked it would have amplified to about -20 dBm.
