MICROWAVE GROUP DELAY TIME ADJUSTER USING RESONANCE CIRCUIT

摘要

A microwave GD(Group Delay) time adjuster using a resonance circuit is provided to properly adjust GD time changed by various factors, thereby effectively eliminating nonlinear distortion signals or channel interference signals. An input stage hybrid combiner(210) is equipped. The first GD time adjuster(220) consists of the first variable capacitor unit(222) including a varactor diode and the first variable inductor unit(224) having the first transmission line. The second GD time adjuster(230) consists of the second variable capacitor unit(232) having a varactor diode and the second variable inductor unit(234) having the second transmission line. An output stage hybrid combiner(240) is equipped.
