Wireless communication apparatus for simultaneously performing multiple wireless communications |
摘要 |
A portable wireless communication apparatus is provided with antenna elements; a mobile phone signal processing circuit; a DTV tuner for receiving DTV low-band frequency signals and DTV high-band frequency signals; impedance matching circuits for the mobile phone signal processing circuit; and impedance matching circuits for the DTV tuner for receiving the DTV low-band frequency signals and DTV high-band frequency signals. A switch is changed to select either the DTV low-band frequency signals or the DTV high-band frequency signals, and output the selected signals to the DTV tuner. A tuner controller controls the switch to select the DTV high-band frequency signals by using the antenna element for transmission from the mobile phone signal processing circuit. |
