Abstract
A multi-band Doherty power amplifier (DPA) is provided. A dual-band Doherty power amplifier (DB-DPA) is based on a 3-way architecture and comprises a main amplifier for each band and an auxiliary amplifier handling both bands. The 3-Way DB-DPA improves the average drain efficiency in concurrent dual-band operation compared to the traditional 2-Way DB-DPA, by avoiding early clipping in the main amplifiers, while benefiting from load-pulling from the auxiliary power amplifier.
