Abstract
The present invention concerns a radio circuit including a local oscillator, a first receive frequency converter, a frequency divider and a demodulator. A receive signal and an output of the local oscillator are input to the first receive frequency converter. The receive signal is converted into a first intermediate signal by the first receive frequency converter, and the first intermediate frequency signal is input to the demodulator. The output of the local oscillator is frequency-divided by the frequency divider and also input to the demodulator. The signal converted into the first intermediate frequency is demodulated into a baseband signal by the demodulator.
