I need someone's suggestion over the phase shifting.
RF circuit design is kind of new for me. I am currently doing a fully differencial LNA, S11=-11.4dB, S22=-5.6dB, Gain =19.8dB, NF=2.23dB, but my input signals and output signals have 23% apart from each other in a period.
Is the design good enough especially the phase shifting? How can I improve the S-parameter?
Thanks in advance~~~:smile:
