Abstract
A microwave amplifier includes a bias circuit including a micro-strip line and a capacitor for biasing an output line of a FET with a DC voltage, and a filter block implemented by a low-pass-filter or a band-rejection-filter and a capacitor serially connected between the output line and the ground. The filter block passes a beat frequency generated by two of the carrier signals included in the input signal of the FET while maintaining the carrier signals on the output line.
