Hello Everyone;
I want to use an amplifier in the UHF band (around 700MHz) with about 100MHz bandwidth. It should be with low IM3 distortions. I have used GALI-51 from minicircuits, but it seems to have IM3 distortions. Is there any aternative for GALI-51 gain block? If I want to design a transistor amplifier, what is the best transistor? What is the best design approach? Which book may help me?
Dear No One,
Nothing is free from IP3, but you have not specified your IP3 requirements.
While GALI-51's IP3 is about 35dBm, you might want to check WJ's
AH215 (IP3 46dBm) or AH312 (IP3 49dBm).
These consume a lot of power.
