Abstract :
An automatic gain control amplifier for automatically leveled output power, broadband, swept-frequency applications to 3 GHz has been developed. Consisting of a variable- pi attenuator, four additive-gain amplifier stages, a temperature-compensated peak detector, and an output buffer, the amplifier features a maximum leveled gain of 22 dB, a gain control range of 25 dB good input and output matches to 50 Omega , and suppressed second-harmonic distortion. It operates with +or-6-V power supplies and dissipates approximately 800 mW.<>
