Patent ID: 7899411

Claim:
A RF integrated circuit (IC) comprising: a processing module, that generates a first control signal to select either a receive mode or a transmit mode for a first RF transceiver, the first control signal having a first value when the receive mode is selected and a second value when the transmit mode is selected and that generates a second control signal to select either a receive mode or a transmit mode for a second RF transceiver, the second control signal having a first value when the receive mode is selected and a second value when the transmit mode is selected; a first transmit/receive switch, coupled to the first RF transceiver and the processing module, that couples the first transmit signal to a first antenna when the first control signal has a second value, and that produces the first received signal based on a first inbound RF signal to the first antenna when the first control signal has a first value, wherein the first transmit/receive switch includes a first on-chip microelectromechanical switch; and a second transmit/receive switch, coupled to the second RF transceiver, and the processing module, that couples the second transmit signal to a second antenna when the second control signal has a second value, and that produces the second received signal based on a second inbound RF signal to the second antenna when the second control signal has a first value, wherein the second transmit/receive switch includes a second on-chip microelectromechanical switch.
