Abstract

PURPOSE: To keep the output power constant against the fluctuation of the power supply voltage for the portable radio apparatus or the like by providing the constant voltage circuit to the DC power source.
CONSTITUTION: The constant voltage circuit is formed with the serial circuit of constant voltage diode CD1 and resistance R4, and no change is caused due to the function of the constant voltage circuit for the current which flows to the voltage devision circuit in which impedance circuit C and resistance R3 are connected in series against the fluctuation of power supply voltage Vcc. Accordingly, the initial setting state never changes, and the current flowing to driver amplifier (a) and power amplifier (b) can be held constant even with the fluctuation of Vcc. As a result, output power P0 can be kept constant.
