ABSTRACT:
A receiver has a first semiconductor chip and second semiconductor chip for receiving signals of a first radio frequency band, and a communication unit for performing communication using signals of a second radio frequency band. A second mixing unit in the second semiconductor chip uses second local signals supplied from a second local signal oscillator when the frequency of first local signals fed from a first-local-signal-output terminal to a first-local-signal-input terminal is within a predetermined range from the second frequency band, or uses first local signals supplied from the first-local-signal-input terminal when the frequency of the first local signals fed from the first-local-signal-output terminal to the first-local-signal-input terminal is out of the predetermined range from the second frequency band.
