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 output impedance-matching element can be relied upon. In one example, the output impedance-matching element can include an output strip line, a shunt capacitor connected between the output strip line and ground, an output capacitor connected between the output strip line and an output bonding pad, and an inductive strip line connected between the output bonding pad and ground.
