  • Patent number: 6195535
    Abstract: A transceiver is disclosed for use in a wireless handset. The transceiver includes a switch for connecting an antenna, one at a time, to a receiver or to a transmitter. In a reception sub-frame, a limiting circuit switches the switch to an attenuated mode when an output signal of the receiver exceeds a predetermined value. The transceiver further includes a disabling circuit which disables the limiting circuit in response to a disabling signal provided to the disabling circuit when the transceiver is in a traffic mode. In addition, a disabling switch is provided which is activated in the traffic mode to provide the disabling signal. The disabling switch includes a light emitting diode, or is included in a controller of the transceiver. The disabling circuit may include a resistive network, an AND gate, a multi-vibrator, or a timer for disabling the limiting circuit in response to the disabling signal.
