<p><P>PROBLEM TO BE SOLVED: To provide a means which is provided with a circuit for corresponding to each transmission power specification even though the transmission power specification of a transmitting side RF signal amplifying part 60 is different because the communication specification of portable radio communication equipment 20 is different in each region (including a country) and avoids an increase in the number of components because the number of components increases when trying to correspond to each transmission power specification by switching of the circuit. <P>SOLUTION: Amplifiers 62, 64 and 65 for transmitting side RF signal amplification generate a control amount of an auto power control voltage signal APCV, an amount corresponding to timing and an output of timing. A CPU 53 can generate each auto power control signal APC corresponding to each transmission power specification by software processing, selects an auto power control signal APC relating to the transmission power specification of the present location and supplies the auto power control signal APC to a D/A converter 70. The D/A converter 70 outputs a value of the auto power control signal APC, an amount corresponding to timing and APCV of timing to the amplifiers 62, 64 and 65. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
