FIELD: equalizing amplitude- frequency response of microwave channels. SUBSTANCE: active corrector of amplitude-frequency distortions has valve connected in series with microstrip line whose first end functions as corrector input. Microstrip line is coupled with quarter-wave short-circuited stub loaded into varactor diode connected to first lead of choke. Second lead of choke functions as control voltage output. Connected to quarter-wave short-circuited stub is input of amplifier whose output is connected to first input of power adder. Second input of power adder is connected to second end of microstrip line and its output functions as corrector output. EFFECT: improved design. 1 dwg
