<p>A system for RX/TX switching of a transmitter and receiver includes a power detector that converts the transmit power level of the transmitter to a detector voltage. The system also includes a comparator that compares the detector voltage to a reference voltage and outputs a control signal to an RX/TX switch that is controlled by the control signal and switches an antenna connection between the transmitter and the receiver. A method for RX/TX switching includes providing a reference voltage corresponding to a desired transmit power level. The method also includes comparing the reference voltage to a detector voltage corresponding to a transmit power level of the transmitter. The method includes controlling an RX/TX switch as a result of the comparison so that the RX/TX switch switches an antenna connection between the transmitter and the receiver, thereby providing half-duplex operation of the transmitter and receiver.</p> |
