Abstract
Unique multi-level power amplifying circuitry is described that may be advantageously utilized in duplex portable radio transceivers which may be inserted into a vehicular adaptor for operation from the vehicle battery. Upon detecting the presence of the vehicular adaptor, the power amplifier may be operated at a second set of power levels which include levels greater than a first set of power levels for portable operation. The multi-level power amplifying circuitry of the present invention may be advantageously utilized in a variety of applications where duplex battery-operated radio transceivers may be inserted into a vehicular adaptor for operation from the vehicle battery.
