    • 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.
    • 接收机具有用于接收第一无线电频带的信号的第一半导体芯片和第二半导体芯片,以及用于使用第二无线电频带的信号进行通信的通信单元。 当从第一本地信号输出端子馈送到第一本地信号输入端子的第一本地信号的频率在其内时,第二半导体芯片中的第二混合单元使用从第二本地信号振荡器提供的第二本地信号 或者当从第一本地信号输出端子馈送到第一局部信号输入端子的第一本地信号的频率时,使用从第一本地信号输入端提供的第一本地信号, 信号输入端从第二频带偏离预定范围。
