Weakly coupled RF network based power amplifier architecture

摘要

RF communications circuitry, which includes a first group of RF power amplifier circuits and a first weakly coupled RF network, is disclosed. The first group of RF power amplifier circuits includes a first RF power amplifier circuit, which receives and amplifies a first RF amplifier input signal to provide a first RF amplifier output signal, and a second RF power amplifier circuit, which receives and amplifies a second RF amplifier input signal to provide a second RF amplifier output signal. The first weakly coupled RF network includes a first pair of weakly coupled RF resonators coupled to the first RF power amplifier circuit and a second pair of weakly coupled RF resonators coupled to the second RF power amplifier circuit.
