I want to build an Automatic gain control (AGC) working at X band (9-10 GHz). Could you plz advise full solution for it with VGA + Coupler + Power detector + Opamp?
Thanks & Best regards,
You could try AD8317 for the detector, which also supports controller mode. See datasheet page 13 and Figure 30. You will need a VGA with wider frequency range than ADL5330 can support.
