Abstract :
Space Solar Power System (SSPS) has been proposed to make use of microwave, and it is important to steer the beams toward the receiving system accurately. To control the phases among numerous transmitters with a high degree of accuracy, it is necessary to correct the output phase variations automatically. Therefore we have developed the automatic correction system of the phase variations generated at the power amplifier. We confirmed that the accuracy of the output signal phase could be below ±1 deg with the system when the power amplifier output level changed.
