Abstract: An antenna receives an RF signal and an RF signal at different frequency bands. An oscillator outputs a local oscillator signal at a frequency f1. An oscillator outputs a local oscillator signal at a frequency f2. A modulator modulates the frequency based on the local oscillator signal at the frequency f1 and the local oscillator signal at the frequency f2, and generates a plurality of local oscillator signals at different frequencies. A frequency converter mixes the plurality of local oscillator signals, at different frequencies, generated by the modulator, with the RF signal and the RF signal, and generates baseband signals of the RF signal and the RF signal. A signal processor performs a predetermined process for the baseband signals generated by the frequency converter.
