Patent ID: 7738840

Claim:
A voice, data and RF integrated circuit (IC) comprising: a first RF transmitter that generates a first transmit signal from first outbound data; a first RF receiver that generates first inbound data from a first received signal; a second RF transmitter that generates a second transmit signal from second outbound data; a second RF receiver that generates second inbound data from a second received signal; a processing module, that generates a first control signal to select either a receive mode or a transmit mode for the first RF transmitter and the first RF receiver, 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 the second RF transmitter and the second RF receiver, 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 transmitter, the first RF receiver 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 transmitter, the second RF receiver 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.
