Abstract

A power amplifier utilizes cascode arrangements to achieve target performance levels for a power amplifier, such as the type used in wireless communication devices. A negative resistance circuit is provided for the cascode arrangement such that high gain, or oscillation, is promoted during operation of the power amplifier. In one embodiment, the negative resistance circuit includes cross-coupling transistors. Various features are provided in order to reduce the susceptibility of the power amplifier to voltage breakdown while maintaining good performance.
