Abstract

A mobile phone device, a radio frequency transceiver circuit and an impedance adjusting device. The present invention discloses a mobile phone device. The mobile phone device comprises a baseband processor, an antenna, a duplexer and a radio frequency transceiver circuit. The antenna is used to receive and send radio frequency signals. The duplexer is electrically connected to the antenna. The radio frequency transceiver circuit is connected to the baseband processor and the duplexer, respectively. The radio frequency transceiver circuit comprises a first power amplifier and an impedance adjusting device. The first power amplifier has a first output impedance. The impedance adjusting device is electrically connected between the first power amplifier and the duplexer, and comprises at least one switch, wherein the baseband processor is connected to and control the at least one switch of the impedance adjusting device to adjust an impedance value of the impedance adjusting device, such that a first load impedance of the first power amplifier and the first output impedance match one another.
