A Doherty power amplifier with extended resonance power divider for linearity improvement

Abstract

A Doherty power amplifier using an extended resonance power divider is designed for linearity improvement. Taking advantage of the class C amplifier input admittance variations as a function of input power level, the extended resonance power divider is designed to provide proper power-dependent power division ratio for improving the linearity of the Doherty… (More)
