Abstract
An amplifier may include a transistor and input and output matching networks. One or more harmonic trap circuits may be electrically connected to a node located between the input matching network and a gate terminal of the transistor or to a node located between the output matching network and a drain terminal of the transistor. Each harmonic trap may provide a low resistance path to ground for signal energy above a fundamental operating frequency of the amplifier, such as harmonic frequencies thereof. The output matching network may act as an impedance inverter that provides a 90 degree insertion phase between the input of the output matching network and the load. A variable length drain feeder may connect a voltage source to an output of the output matching network.
