APPARATUS FOR CONTROLLING VOLTAGE OF POWER AMPLIFIER IN RADIO MOBILE TERMINAL EQUIPMENT

摘要

The present invention relates to the provision of a power amplifier voltage control device to prevent unnecessary consumption of power as imposing a control voltage of a power amplifier provided in the portable communication device using a battery such as a wireless terminal effectively. Therefore, in this invention, as compared to a power amplifier, a transmission automatic gain control voltage value and the comparison voltage value to be output by controlling the amplification degree of the signal to be input according to whether the state of the reference voltage comparison / restricted group for outputting the result, wherein comparing / converting the output from the limiter to the state of the reference voltage will be characterized by a power amplifier control voltage of the mobile station apparatus is composed of parts of the power converter as a reference voltage of the power amplifier.
