Abstract

See full text

A power amplifier circuit for amplifying an envelope modulated Radio Frequency (RF) signal with improved linearity and efficiency includes a power amplifier, and a variable load matching circuit coupled to an output port of the power amplifier. The input impedance of the variable load matching circuit is changed such that an output power of the power amplifier is at a first output power level, or a second output power level which is higher than the first output power level.
