摘要
分析了平衡倍频器的工作原理和结构,并使用商用肖特基势垒二极管DBES105a设计一个W波段宽带三倍频器。电路采用微带线制作,并安装在波导中。倍频器电路的波导微带过渡结构、低通滤波器和匹配枝节均使用电磁场分析软件HFSS仿真。最后在ADS中利用谐波平衡法对倍频器电路进行优化。仿真结果表明,当输入功率为20 dBm时,在80 GHz～100 GHz范围内,输出功率十分平稳,约为5 dBm。
The operating principles and structure of balanced frequency tripler is described.A W-band balanced frequency tripler using commercially available schottky barrier diode DBES105a is designed.The circuit is fabricated with microstrip line and housed in the waveguide block.The waveguide-to-microstrip probe transition,the lowpass filter and the impedance match sections are all analyzed by using EM software HFSS.At last,the tripler circuit is optimized by using Harmonic balance simulation in ADS.The simulated output power is very flat between 80 GHz and 100 GHz,and reaches almost 5 dBm with the input power of 20 dBm.
