In order to improve the power utilization and ensure amplifier operating points consistency, an adaptive power allocation algorithm based on digital and analog hybrid system (APA-DAH) is proposed in this paper, which ensures each amplifier works at the same operating points and assigns each beam power adaptively according to the communication traffic. The power utilization ratio of satellite payload has been improved greatly by the APA-DAH.The amplitude and phase distribution of each channel in APA-DAH should be completely identical, otherwise the performance would be impaired severely for the mutual coupling among signals. An amplitude and phase consistency error calibration algorithm is proposed.The decoupling of calibration signals is realized by using the crosscorrelation orthogonal characteristic of the orthogonal zero correlation zone (ZCZ) sequences in the zero correlation interval , and the normal communication performance is not affected by calibration by reducing the transmit power for the excellent self-correlation characteristic of the ZCZ sequences.Performance simulation and far field test show that under the condition that the calibration signal power is less than the normal signal 15 dB, the amplitude error is better than 0.1 dB, the phase error is better than 0.3 degree, and the gain loss within the main lobe is less than 0.35 dB after calibration.
