This paper presents a broadband (0.5GHz to 2.2GHz) power amplifier with output power up to 25W and drain efficiency up to 69%. Further, its use in an envelope tracking system to achieve high efficiency in backoff over a comparable carrier bandwidth i

In this paper, we present the design of an inverse Class F power amplifier GaN MMIC, specifically designed for an envelope-tracking application. Power transistors are not typically characterized for the drain modulation that is fundamental to envelop

• Digital compensation techniques will allow for removal of most RF “errors” in future wireless transceivers. • The fundamental dynamic range performance limits then become noise (at the low end) and power supply voltage (at the high end).
