Only the effective part of the radio frequency signal is high frequency amplified and output to the antenna duplexer 102. The transmission local oscillation signal is generated by the frequency synthesizer 104 and is an oscillation signal having a frequency according to the control voltage from the control unit 140.

The radio frequency signal from the transmission unit 105 input to the antenna duplexer 102 is the transmission filter 102b.
As a result, only the radio frequency signal in the transmission band is transmitted to the antenna 101.
And is radiated into space toward the base station BS. The radio frequency signal in this transmission band is not input to the reception unit 103 by the reception filter 102a.
