发明名称 Antenna sharing switching circuitry for multi-transceiver mobile terminal and method therefor
摘要 <p>Antenna switching circuitry in a multi-transceiver mobile terminal 10, which features a first switching unit (SW1) which controllably couples a first transceiver port (P1) to either a first antenna port (PA1) or a second antenna port (PA2);and a second switching unit (SW2) which controllably couples the second antenna port (PA2) to either the first transceiver port (P1), through the first switching unit (SW1), or to an input/output port (PI/O) of a second transceiver (12). According to this scheme, the second antenna port is coupled to the input/output port of the second transceiver (12) in a mode in which the second transceiver (12) is operational, the first transceiver port (P1) being decoupled from the second antenna port at this time, wherein the first transceiver port is coupled to the first antenna port and the input/output port of the second transceiver (12) is decoupled from the second antenna port, when the first transceiver is in a transmit mode, and wherein the first transceiver port is coupled to either of the first and second antenna ports, when the first transceiver (11) is in a receiving mode and the input/output port of the second transceiver (12) is decoupled from the second antenna port. &lt;IMAGE&gt;</p>
