1. A multiple-mode transceiver, comprising:

  • an antenna switch configured to selectively connect a first antenna switch node to one of a second antenna switch node, a third antenna switch node, or a fourth antenna switch node;

    a receiver switch configured to selectively connect a first receiver switch node to one of a second receiver switch node or a third receiver switch node, the second receiver switch node being connected to the third antenna switch node;

    a transmitter switch configured to selectively connect a first transmitter switch node to one of a second transmitter switch node or a third transmitter switch node, the second transmitter switch node being connected to the fourth antenna switch node;

    a receiver module configured to receive and process incoming signals and to generate a mode control signal based on the incoming signals, the receiver module being connected to the first receiver switch node;

    a transmitter module configured to generate outgoing signals, the transmitter module being connected to first transmitter switch node;

    a duplexer configured to simultaneously pass the incoming signals and the outgoing signals, the duplexer having an antenna transmit/receive node connected to the second antenna switch node, a device receiver node connected to the third receiver switch node, and a device transmitter node connected to the third transmitter switch node; and

    a controller configured to generate, in response to the mode control signal, an antenna switch control signal to control operation of the antenna switch, a receiver switch control signal to control operation of the receiver switch, and a transmitter switch control signal to control operation of the transmitter switch.
