<P>PROBLEM TO BE SOLVED: To perform the ON/OFF control of a transmission power source without deteriorating the quality of a received signal. <P>SOLUTION: A control circuit 17A has a PE bit detecting function 17a and a transmission power source timing control function 17b. A PE bit is respectively detected from packet data received in a receiving slot just before and just after a transmitting slot and during such a PE bit period, the supply of a transmission power source voltage Vtx to a transmission circuit 5 is turned on/off. <P>COPYRIGHT: (C)2003,JPO |
