  • SHARED ANTENNA CONTROL
    Publication number: 20110176527
    Abstract: A scheme for sharing antenna control pins in a wireless communications device implemented on a single CMOS integrated circuit is described. By providing a routing circuit for coupling the antenna control signal to the appropriate transceiver circuitry in a multi-transceiver system, antenna control signals may be efficiently processed using a minimum of pins on the wireless communication device.
    Type: Application
