    • Receiving sensitivity deterioration in wireless communication due to a spurious radiation wave generated from a card reader/writer is suppressed in a case where a mobile phone terminal is provided with a contactless IC card reader/writer or a contactless IC card. The mobile phone terminal provided with the contactless IC card reader/writer performs measurement of a wireless status upon reception (step S1) and transmission power wetting (step S2), and when an instruction to start a reader/writer function is inputted from a user (step S3), wireless status deterioration due to spurious radiation from the reader/writer is predicted (step S4). Then, the mobile phone terminal judges whether control to reduce the transmission speed is necessary or not, on the basis of a value of the deterioration predicted wireless status (step S5), and when judged necessary, the transmission speed is reduced (step S6).

    • A modulated signal from an orthogonal modulator is supplied to a mixer, and a second local oscillating signal from a second local oscillator is supplied through a variable gain amplifier to the mixer. A transmission signal from the mixer is supplied through a step-attenuator (ATT) to a power amplifier, and further supplied through a directional coupler and an isolator to an antenna. A signal from the directional coupler is supplied through a detector to a comparator, and a reference voltage from a reference voltage setting unit is supplied to the comparator. An output from the comparator is supplied to a control unit of the variable gain amplifier and a gain is thereby controlled such that a DC voltage from the detector and the reference voltage from the reference voltage setting unit become equal to each other. Further, an attenuation amount of the step-attenuator is set by an attenuation amount setting unit in accordance with a transmission output control signal from a base station.

    • A radio communication terminal has a plurality of matching circuits that optimize the efficiency of a power amplifier for a range of different battery voltages. A first matching circuit optimizes the efficiency of the power amplifier for a battery voltage higher than a predetermined threshold value. A second matching circuit optimizes the efficiency of the power amplifier at a voltage lower than the threshold value. A control section compares a detection result of a battery voltage from a voltage monitor section with the threshold value, and performs switching between the plurality of matching circuits.
