Abstract
Apparatus and methods for a modified Doherty amplifier operating at gigahertz frequencies are described. The combining of signals from a main amplifier and a peaking amplifier occur prior to impedance matching of the amplifier's output to a load. An integrated distributed inductor may be used in an impedance inverter to combine the signals. A size of the impedance element can be selected by patterning during manufacture to tune the amplifier and to allow power scaling for the amplifier.
