Assignee: FALCOMM, INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A dual-drive based Doherty amplifier, comprising:
a first power amplifier; and
a second power amplifier that is in parallel with the first power amplifier,
wherein the first power amplifier is configured to receive a first portion of a signal having a first phase,

wherein the second power amplifier receives a second portion of the signal having a second phase that has a phase difference from the first phase, and wherein at least one of the first power amplifier or the second power amplifier includes a dual-drive power amplifier core, and
wherein the dual-drive power amplifier core includes:
a transistor differential pair, each transistor having a gate terminal, a drain terminal, and a source terminal; and
a multi-feed coupling network configured to:
drive the dual-drive power amplifier core out-of-phase at the gate terminal and the source terminal by allowing the transistor differential pair to be driven out-of-phase at the gate terminal and the source terminal; and
allow the source terminal and the drain terminal to swing in-phase.
