Abstract:
A radio communication apparatus having a high-frequency power amplifier module at a transmitter-side output stage, and an antenna connected to said high-frequency power amplifier module, said high-frequency power amplifier module comprising:an input terminal; an output terminal; a control terminal; a first voltage terminal; a second voltage terminal; a power amplifier formed by connecting a plurality of transistors in parallel each of which has a first terminal, a second terminal and a control terminal for controlling a current flowing between said first and second terminals; first capacitors and first resistors connected in series between said input terminal and said control terminals of said transistors so that said capacitors are connected on said input terminal side while said resistors are connected on said control terminals side; and second resistors connected between said control terminal and the nodes of said first capacitors and said first resistors that are connected to said control terminals of said transistors, wherein said output terminal is connected to said first terminals of said transistors, said first voltage terminal to said first terminals of said transistors, and said second voltage terminal to said second terminals of said transistors.
