ABSTRACT:
A phase stable limiting power amplifier includes a transistor, having a bias voltage applied to the collector and one applied to the base for operation in a class AB configuration. Input impedance matching circuitry may be coupled to the base with output impedance matching circuitry coupled to the collector. The input and output impedance matching circuitry may include only reactive elements for maximizing amplifier gain. Instability suppression circuitry may be connected between the base and the emitter. Representative functional characteristics for facilitating component selection and selection of operation conditions are provided.
