Hello,there is a circuit shown below taken from the attached article, where we put a YIG signal to a cavity resonator(from A to B) .
Then for feedback we lock on the point of the dip.
why do you think they use 33dBm to amplifier the YIG and 30dB to amplify the supressed carrier signal(after amplifier).
is there some intuition which could help me understand why they use such high amplifications?
Thanks.
Thanks.
