一种小体积低功耗微波倍频电路

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。

Small Size and Low Power Dissipation Microwave Frequency Multiplier

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.
