微波倍频电路的设计

Design of Microwave Frequency Multiplier Circuit

论述微波倍频器的基本设计原理及一种S波段三倍频电路的设计方法。实验结果表明,用这种方法设计的倍频电路,除损失理论上的相位噪声外,几乎不附加噪声,同时倍频效率也比较高。因此,在研制低相噪频率综合器时,采用这种倍频器是非常有用的。

This paper discusses the fundamental principle on designing microwave frequency multiplier, and the method of designing a kind of S-band microwave frequency multiplier. The experimental result shows that the frequency muhiplier designed by this method can hardly add noise except the theoretic phase noise loss. In addition, the efficiency of the frequency multiplier is relatively high. So, it is very useful to adopt this kind of microwave frequency multiplier in developing the low phase noise frequency synthesizer.
