宽带微波相关器的仿真与实现

Simulation and Implementation of Wideband Microwave Correlator

摘要:

为了解决高精度瞬时测频（Instantaneous Frequency Measurement，IFM）接收机中高性能微波相关器的设计问题，呆用高频率仿真系统（High Frequency Simulation System，HFSS）进行软件仿真。根据软件仿真结果，在同一介质基片上设计制作了含有功分器、3dB正交电桥和检波器的一种X波段带状线结构微波相关器实际电路。测试结果表明，该结构的微波相关器在8～12GHz频率范围内具有良好的性能，且具有体积小、工艺简单、调试方便的特点。
