<P>PROBLEM TO BE SOLVED: To achieve improvement in performance of an APC, without considerably modifying the configuration of an existent article, by reducing a radio communication device in size, reducing costs and saving power by decreasing the number of A/D converters to be used for the radio communication device. <P>SOLUTION: In a radio communication device, a receiving circuit includes an A/D converter and communication is performed while alternately switching a transmitting operation and a receiving operation. In the radio communication device, at least one of a transmission power detecting signal for accomplishing an auto power control function for transmission power of a transmitting circuit, a temperature detecting signal for a transmission power amplifier and a temperature detecting signal for a transmitting RF section is converted by the data A/D converter via an input/output switching means. <P>COPYRIGHT: (C)2010,JPO&INPIT |
