<p>PROBLEM TO BE SOLVED: To offset only the frequency of a reception local signal below a reception channel interval, without setting the phase comparison frequency of synthesizer to be low. SOLUTION: At the time of a reception operation, a base band signal processing part 51 generates the single tone signal of a frequencyΔf as a transmission base band signal. A transmission high frequency part 61 generates a tone signal which is frequency-offset from a reception carrier frequency byΔf, by using a local signal from a synthesizer part 41 based on the transmission base band signal and the signal is used as the local signal for down conversion in a reception high frequency part 31.</p> |
