Abstract
According to an embodiment of the disclosure, a series or source feedback is provided to a solid-state power amplifier to achieve improved amplifier output power, good impedance match, and low voltage standing wave ratio (VSWR). In an embodiment, an inductive element is coupled to the source of the power amplifier transistor to serve as a series or source feedback for the transistor. In an embodiment, a high-impedance transmission line such as a microstrip or coplanar waveguide is provided as an inductive element coupled to the source of the transistor. In an embodiment, a series or source feedback is provided to each amplifier in a multistage amplifier circuit.
