Abstract

PURPOSE: To perform adjustment continuously to obtain the optimum value of the frequency characteristic, by constituting the means, which adjusts the degree of the impedance coupling and the signal frequency, by a coaxial waveguide converter.
CONSTITUTION: The signal wave input from signal input waveguide 21 passes through the impedance transformer circuit due to signal coaxial waveguide converter 31 and is connected to varactor 24 and is amplified and is output from I/O waveguide 21 through the same course. Here, the gain of the amplifier is adjusted by adjusting the impedance transformer continuously.
