Automatic Gain Control (AGC) in Receivers - QSL.net
www.qsl.net• A simple method of gain control would involve the use of a variable attenuator between the input and the first active stage. Such an attenuator, however, would decrease the signal level, but it would also reduce the S/N of any but the weakest acceptable signal. • A typical AGC loop circuit is shown in the picture below.

Detection and Measurement of Radar Signals: A Tutorial
www.its.bldrdoc.govThe variable Pr takes the place of Pp in Eq. B-1, and the value for the external attenuation, Aext, becomes: (B-3) where all variables are as defined for Eq. B-1. For example, suppose a radar transmitter operates at 2800 MHz; that the transmitter produces 1 MW peak power (+90 dBm); that the transmitter antenna gain is +35 dBi; that the
