摘要： The transmission apparatus and transmission power controlling method are able to keep high speed feedback control and control transmission power accurately. Polar modulation transmitter (100) is provided with LPF (108) that performs waveform shaping of output power of PA (103) and ADC (109) that obtains output power data for each mode by sampling filtered signals in compressed mode and filtered signals in uncompressed mode at the same phase as the filtered signals in compressed mode. In this way, the phases of sampling signals before and after the mode change are the same, so that it is possible to obtain sampling signals of the same condition before and after the mode change, from filtered signal waveforms. According to feedback control based on these sampling signals, even if drift components remain in the filtered signals, the influence can be ignored, so that it is possible to keep high speed feedback control, and estimate and control transmission power accurately.

摘要： As explained above, according to embodiments of the present invention, by providing averaging section 111 that detects an average power value of amplitude component signals, and controlling transmission power based on the amount of drift in the average output power value of PA 103 and the amount of drift in the average power value of amplitude component signals, when residual drift components are included in the average output power value of PA 103, the influence of residual drift components can be eliminated and transmission power can be controlled, so that it is possible to improve the accuracy of transmission power control. That is, deterioration of power estimation accuracy resulting from residual drift components can be reduced, so that it is possible to satisfy the restrictive requirement that the difference between transmission power be within, for example, the range of +/−0.5 dB.

摘要： When switching the mode of a power amplifier between compressed mode and uncompressed mode, accurate transmission power control is realized. A transmission power control method includes setting a power setting value of mode to switch to, such that an inter-mode output power error is canceled (equal to step ST21), calculating an intra-mode output power error from the power setting value of the mode to switch to (equal to step ST23), calculating a gain linearity value based on the power setting value of the mode to switch to and an output power error of the intra-mode (equal to step ST24), and resetting the power setting value of the mode to switch to based on the gain linearity value (equal to steps ST25 and 26).
