介绍了一种机载合成孔径雷达频率合成器的实验研究。该合成器采用了直接合成与数字锁相相结合的方法，并采用了超轻型、双重隔振技术和高效率开关电源。实现了低功耗、轻重量、小体积和低相位噪声。最后给出了研制结果和实验结论。

An experimental study on frequency synthesizer of are airborne radar is described. Direct synthesizing and phase locked loop are combined to implement the synthesizer. Ultra-light and double shock proof and high efficiency switching power supply are used in the synthesizer. Low power consumption, lightweight, small size and low-phase noise are obtained. The experimental results and conclusion are given at the end of this paper.
