ABSTRACT:
A radio transceiver includes means to switch from the transmit to the receive mode. The disclosed squelch circuit operates in the receive mode to mute and unmute the receiver at different received signal levels to prevent undesirable muting during signal fading conditions. The squelch also provides a means to mute the receiver for a sufficient period allowing switching transients to die out after the transceiver has been switched from the transmit to the receive mode.
