    摘要： Impedance mismatching by a matching circuit provided on a signal line which connects a first common terminal and a second common terminal is eliminated so as to significantly reduce insertion loss of a switch module. Therefore, it is possible to provide a switch module which has a simple configuration without the need for connection of a matching circuit to antenna terminals to which antennas are respectively connected, and is able to selectively connect any one of the antennas and any one of communication systems.

    摘要： Switching network for diversity receivers. In some embodiments, a receiver can include an input node and an output node, and a first amplification path having a first amplifier implemented between the input node and the output node. The receiver can further include a second amplification path having a second amplifier implemented between the input node and the output node. The receiver can further include a switch implemented to selectively couple the first amplification path and the second amplification path.

    摘要： RF front end circuitry includes primary transceiver circuitry associated with a primary antenna and secondary receiver circuitry associated with a secondary antenna. Generally, the primary transceiver circuitry and the primary antenna are located on one end of a mobile communications device, while the secondary receiver circuitry and the secondary antenna are located at an opposite end of the device. Cross-coupling connection lines run between the antenna switching circuitry for the primary antenna and the secondary antenna, and are reused to send a portion of primary RF transmit signals from the primary transceiver circuitry to the secondary receiver circuitry so that primary RF transmit signals coupled into the secondary receiver path via antenna-to-antenna coupling can be reduced.
