A voice, data and RF integrated circuit (IC) includes an RF transmitter
that generates a transmit signal from outbound data. An RF receiver that
generates inbound data from a received signal. A processing module
generates a control signal to select either a receive mode or a transmit
mode for the RF transmitter and the RF receiver, the control signal
having a first value when the receive mode is selected and a second value
when the transmit mode is selected. A transmit/receive switch couples the
transmit signal to an antenna when the control signal has a second value,
and produces the received signal based on an inbound RF signal to the
antenna when the control signal has a first value, wherein the
transmit/receive switch includes an on-chip microelectromechanical
switch.
