Abstract
A power amplifying apparatus for a mobile phone is provided. In the power amplifying apparatus, a power amplifier uses a transistor as a power amplifying device, and a non-volatile memory pre-records the static characteristic measurement data of the transistor. A DC bias current of the transistor is controlled according to transmission power of the power amplifier referring to the static characteristic measurement data, by changing a gate voltage of the transistor, by changing a drain voltage of the transistor with the gate voltage fixed, or by changing both the gate voltage and the drain voltage.
