高性能跳频滤波器设计
资料介绍
提出了一种用无源谐振腔和有源电路相结合来实现高性能跳频滤波器的方法，利用开关电容阵加载腔体实现高速宽带低损的频率跳变。重点对这种跳频滤波器的插损和功率两个指标进行分析，包括腔体无载品质因数、PIN开关的功率和插损、加载射频电容的插损。利用三维电磁仿真软件HFSS和平面电路仿真软件ADS，结合具体的技术指标要求，给出了跳频滤波器部分电路的仿真曲线和测试结果。本滤波器具有高速、宽带、低损、体积小和数控的特点，因此可以广泛应用于跳频通信、软件无线电等领域。
A high- performance frequency- hopping（FH） filter is designed by using the method of the active switched capacitor load to passive resonator. The switched capacitor array loaded cavity is used to realized high - speed broadband low- loss frequency hopping. The two indexes（insertion loss and power） of the FH filter, including cavity unloaded quality factor,switching power and insertion loss, insertion loss of load RF capacitance are analysed. By using three - dimensional electromagnetic simulation software HFSS and planar circuit simulation software ADS, part corresponding simulation curves and test results of the filter are provided according to specific technical requirements. This filter is featured by high- sp...
