1. transmit and calibrate the transmitter of phase signal and amplitude signal, comprising:

  • Phase modulation path, for transmitting this phase signal;

    Modulation and Amplitude Modulation path, for transmitting this amplitude signal;

    Control unit, for postponing in this phase modulation path and this Modulation and Amplitude Modulation path the signal at least one;

    Alignment unit, in the calibration mode, this alignment unit provides the first calibrating signal using as this phase signal, and provides the second calibrating signal using as this amplitude signal, and wherein, this first calibrating signal is identical with this second calibrating signal;

    AndDigital modulator, in the normal mode, this digital modulator modulation I/Q data are to provide this phase signal and this amplitude signal respectively to this phase modulation path and this Modulation and Amplitude Modulation path;

    Wherein, described control unit, also for the difference of detecting the first calibrating signal after phase modulation path transmission and the second calibrating signal after Modulation and Amplitude Modulation path transmission under this calibration mode;

    And to postpone in this phase modulation path and this Modulation and Amplitude Modulation path the signal at least one according to this detecting result.
