Truly one of the most remarkable achievements in modern-day communications technology has been the advent of linearization of power amplifiers. It remains a difficult task to design a power amplifier that simultaneously provides very wide bandwidth, high gain, high linearity, and high efficiency. These power amplifier design goals are usually only reached in a reasonable trade space in which one or more goals are traded at the expense of one or more other goals, depending on the end-use requirements. GaN based PA technology has the promise of maximizing bandwidth*Gain, linearity and efficiency with some linearization assist electronics. This proposal seeks to develop high-efficiency, GaN based power amplifier technology for handling arbitrary band and bandwidth signals that exhibit various envelope modulation characteristics. Benefits: The proposed effort is expected to be beneficial to a number of military and commercial applications since the general direction for wireless data transmission is for wider bandwidth and more complex signaling formats due to the need for increased information flow requirements and spectrum preservation requirements.
