Abstract
A radio antenna switch module for a high frequency radio transceiver enables the radio transceiver to have a small number of receivers and transmitters and a larger number of antennas, whereby each antenna has a different diversity characteristic. The diversity between antennas provide for greater communication reliability, while the small number of receivers and transmitters allows the transceiver to operate at relatively low power compared to conventional radio transceivers. The switch module also allows for two loopback modes between the transmitter and the receiver for at-speed, low-cost self-test in production.
