AGC Loop(АРУ)based on AD8317+opamp+VVA

Logarithmic Detector AD8317, switched to Controller Mode, connected to Amplifier Output via directional coupler and attenuator, measuring level and send output voltage to operational amplifier, configured like invertor, then, inverted voltage value going to VVA (voltage variable attenuator) on input of our amplifier and compensating losses on output of amplifier. Vset point of AD8317 tuned precision for used range.
Now it’s have linear compensation range 3dB, and it’s more then enough in my case.
