BRIDGE_WITH_AGC_ON_BOTH_DIODES
Agc is applied to center tap of transformer, to turn one diode off while other is being turned on. Attenuation can be 40 db over bandwidth up to 250 Mc with agc bias of 0.5 to 3 v. Insertion loss is only a few db.-W.A. Rheinfelder, Designing Automatic Gain Control Systems, EEE, 13:1, p 53-57.
