Low-pass filter serves as loop giving dosed-loop bandwidth of at least 5 kHz. Loop operates in square-law region of de-tector diode. Inputs to IF amplifier are in range from -60 dBm to -to dBm, and AGC action provides 30-MHz IF output of -15 dBm. Power splitter ensures that detector also operates at -15 dBm. Article gives design equations and performance curves.-R. S. Hughes, Design Au-tomatic Gain Control Loops the Easy Way. EDN Magazine, Oct, 5, 1978, p 123.128.
