| 摘要 |
The polar modulation apparatus of the present invention can control the output power of a transmission signal over a wide range and compensate characteristic degradation reliably upon temperature change. Polar modulation transmission apparatus 100 is provided with: temperature sensor 120; temperature compensation section 1601 that corrects an amplitude signal and performs temperature compensation for transmission power amplification section 190; temperature compensation section 160-2 that corrects a power amplification signal and performs temperature compensation for power adjustment section 180; and correction value setting section 130 that sets correction values for temperature compensation section 160-1 and temperature compensation section 160-2, and, while only the amplitude signal is corrected according to a measurement result in temperature sensor 120 in the first mode, the amplitude signal and the power adjustment signal are corrected according to a measurement result in the second mode.
