In this paper,with the help of double balance mixer,design and manufacture of S-band wide-band & frequency multiplier chain is introduced,of which bandwidth is biggerthan 13%,harmonic rejection is bigger than 45 dB,output fluctuation is less than 1 dB.

• 本文介绍使用双平衡混频器设计制作S波段宽带八倍频链带宽大于13%25，谐波抑制大于45dB、输出波动小于1dB的良好性能。
