ABSTRACT:
In a radio communication device of a CDMA system selectively operable in high and low power modes to receive a reception analog signal and to produce a demodulated signal, an A/D converter is controlled to reduce power consumption in the low power mode in comparison with the high power mode. The reduction of power consumption can be established by partially operating the A/D converter or by lowering a sample rate in the low power mode. A despreading portion connected to the A/D converter is also controlled in a manner similar to the A/D converter. Each of the high and the low power modes is indicated by a mode control signal produced by a CPU controller.
