  • This paper introduces the phase reverse system designed for SLAC Energy Doubler (SLED) based on Field Programmable Gate Array (FPGA). The phase reverse system is composed of a microwave IQ vector modulator, a FPGA board with the high speed DAC unit. Modulated by the DAC output pulse signal, the IQ modulator transforms the RF CW input signal into 4 s pulse output signal, whose phase is reversed to 180 at the moment of 3 s. The test results show that the phase reversal accuracy is about 1802, and the stability is better than 0.5. The RF power gains of six SLEDs are more than 7 dB, the maximum 7.54 dB is achieved. The long-term variation of the power gain is 0.1 dB.
