Title: 90-DEGREE LUMPED AND DISTRIBUTED DOHERTY IMPEDANCE INVERTER
Abstract:
Apparatus and methods for a modified Doherty amplifier operating at gigahertz frequencies are described. The combining of signals from a main amplifier (132) and a peaking amplifier (138) occur prior to impedance matching of the amplifier's output to a load. An integrated distributed inductor (510) may be used in an impedance inverter to combine the signals.
