BALANCED RADIO FREQUENCY POWER AMPLIFIER, RADIO FREQUENCY FRONT-END MODULE, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2024/067226

A1

A balanced radio frequency power amplifier, a front-end module, and a corresponding electronic device. The balanced radio frequency power amplifier comprises a driving-stage power unit (101, 201), an inter-stage power divider (102, 202), a main path power amplifier (103, 203), an auxiliary path power amplifier (104, 204), a first output matching network (A105, A205), a second output matching network (B106, B206), and an output power combiner (107, 207). A symmetrical balance design is used for the main path power amplifier (103, 203) and the auxiliary path power amplifier (104, 204), so that the impact of the change in the antenna voltage standing wave ratio (VSWR) on the transmission power and the transmitting efficiency is overcome to the greatest extent. Moreover, a 3 dB distributed orthogonal coupler is used for the inter-stage power divider (102, 202) and the output power combiner (107, 207), so that performance indicators of the radio frequency power amplifier such as the area size, the bandwidth, the insertion loss, and the transmitting efficiency are optimally balanced and optimized.
