ABSTRACT:
A mobile communication device includes power supply control switches corresponding to a local oscillator, transmitting frequency converter, receiving frequency converter, receiving amplifiers and transmitting power amplifier in a radio unit, and a battery saving control circuit in a control unit. By individually controlling the ON timing of the switches by means of the battery saving control circuit, it is possible, prior to a time slot period allocated to an individual mobile station, first to supply power to the local oscillator, then supply power to the frequency converters, and then supply power to amplifiers. By doing so the mobile communication device is set in a standby state for transmitting/receiving operation.
