摘要： The dual mode power amplifier apparatus of the present invention is comprised of a number of power amplifiers (101-103) coupled to a voltage convertor (104) through their collector supply lines. A mode select line (105) is connected to the voltage convertor (104) to select a digital or analog mode. The preferred embodiment of the present invention is used in a hybrid digital/analog radiotelephone. In the digital mode, the voltage convertor (104) is turned off and the voltage convertor (104) supply voltage is allowed through to the collectors of the power amplifiers (101-103). This permits the power amplifiers (101-103) to operate with optimum linearity in a digital transmission environment. In an analog environment, the voltage convertor (104) is on and supplying a reduced voltage to the power amplifiers (101-103) allowing more efficient operation in this mode.
