RADIO FREQUENCY POWER AMPLIFIER MODULE AND MOBILE COMMUNICATION TERMINAL

摘要

A radio frequency power amplifier module and a mobile communication terminal are disclosed, the radio frequency power amplifier module involves: a radio frequency power amplifier, a power control circuit and an output matching network, the radio frequency power amplifier is used for amplifying the power of the input radio frequency signal, the power control circuit is used for controlling the output power of the radio frequency power amplifier, the input terminal of the output matching network is connected with the output terminal of the radio frequency power amplifier to realize the output terminal impedance matching of the radio frequency power amplifier. The output matching network is realized by integrating the passive device on the Integrated Passive Device (IPD) die, the passive device at least includes an inductance element and a capacitance element. The present application could significantly reduce the size of the radio frequency power amplifier module, simplify packaging process and greatly reduce the whole cost of the module at the same time.
