Patent abstract
A radio frequency circuit includes a radio frequency signal source which produces a radio frequency signal, a power amplifier which power amplifies the radio frequency signal from the radio frequency signal source, and a control unit which controls an output power of the power amplifier. Particularly, the control unit is configured to hold control data defining a relationship among an output power, a gain, and an operation bias point of the power amplifier and adjust the operation bias point of the power amplifier based on the control data such that the output power of the power amplifier is set into a level designated by an external power designating instruction.
