A METHOD OF CONTROLLING A LINEAR POWER AMPLIFIER

摘要

A method of controlling a linear power amplifier (15) comprises inputting an instantaneous input signal (2); filtering the instantaneous input signal to generate a filtered input signal (5); combining the instantaneous input signal (2) and filtered input signal (5) to generate a modified drain source voltage Vds waveform (12); and modulating a switched mode power supply (14) to the linear power amplifier in accordance with the modified Vds waveform. ® KIPO & WIPO 2007
