I am looking for a LNA-Die working from 20 GHz to 24 GHz. actually, i prefer to find a unmatched one although i found all of the productes matched.
anyway, my question is here that when the LNAs such as HMC342 are OFF, without biasing, how much isolation between the in/out port we can have ?
Moved to RF and Microwave.
Isolation between RF in/out unbiased is not a parameter that is measured for amplifiers. Why is this a concern?
What we measure is the reverse isolation, RF out/in with the amplifier biased.
