Abstract

Power amplifying device, including a transistor amplifier of the input signal, mounted with common emitter at least as regards the polarization, and a base biasing device of said transistor amplifier including a first auxiliary transistor that provides the bias voltage of said amplifier transistor, characterized in that said biasing device also includes an auxiliary transistor, called a regulation transistor, mounted with a common emitter, whose collector is coupled to the base of the first auxiliary transistor, the emitter of which is coupled said transistor amplifier and the emitter of the regulating transistor, the latter by means of a first diode, at the same fixed potential point and the base of the regulating transistor being connected to the base of said amplifying transistor by means of a second diode, and because the transistor amplifier, the regulating transistor and the first diode are very in the same radiator, while the second diode is placed outside this radiator.
