摘要： 针对微型相干布居囚禁（CPT）原子频标开展了小型、低功耗微波电路的研究，借助于ADS仿真，设计并实现了一种利用微带线传输微波，以阶跃恢复二极管作为非线性器件的小体积、低功耗微波倍频电路，电路面积为20mm×10mm、功耗小于10mW。测试结果表明：当输入功率为6dBm、频率为569.5MHz的信号时，获得了所需要的频率为3417MHz、功率为-9dBm的微波输出，满足CPT原子频标对微波信号的需求。

Abstract: In order to meet the requirement of the miniature Coherent Population Trapping (CPT) atomic frequency standard, we have studied a small-size and low power consumption microwave circuit. By means of ADS simulation, we have designed and realized small size and lower dissipation microwave circuit with a step recovery diode as the nonlinear device, and the microstrip guiding microwave. The size of the circuit is 20mm×10mm and power consumption is less than 10mW. The measured results show that when the power of input 569.5MHz signal is 6dBm, the circuit generates the wanted 3417MHz microwave signal with -9dBm output power, the output microwave satisfies the requirement of the designed CPT atomic frequency standard.
