Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A power amplifier circuit, comprising: a power amplifier configured to amplify an envelope modulated radio frequency (RF) signal; and a variable load matching circuit coupled to an output port of the power amplifier, the variable load matching circuit configured to have an input impedance that is changeable so that an output power of the power amplifier changes between a first output power level and a second output power level which is higher than the firs…
