Patent ID: 7719141

Claim:
A switching system operable in a transmit mode and a receive mode, the switching system comprising: a transmit port coupled via a transmit path to an input/output port; a receive port coupled via a receive path to the input/output port; and a switching circuit in the receive path, the switching circuit comprising a switch device comprising an input terminal, an output terminal, and a control terminal to receive a control signal that controls a state of the switch device between an on state and an off state; wherein, when the switch device is in the on state, the switching system is adapted to operate in a transmit mode in which the transmit port is operatively coupled to the input/output port and the receive port is at least substantially isolated from the input/output port; and wherein, when the switch device is in the off state, the switching system is adapted to operate in a receive mode in which the receive port is operatively coupled to the input/output port.
