基于LTCC小功率分配器设计与实现

Design and implementation of miniwatt divider based on LTCC technology

利用一套合成滤波器的分析方法,给出了电路元件的各个数值,用电路与电磁仿真软件合成出具有良好性能的滤波器,并且使用ADS 2009及HFSS 13.0软件设计了通频带为2 225~2 700 MHz的二端口功率分配器。通过原理分析、设计仿真,总结并得出为了让滤波器性能表现良好,只需要预先设定好两个反射零点与两个匹配品质因子,就能有效地合成出各个器件的数值。设计具有一定的灵活性,也可以根据不同的滤波器规格设定不同的参数,在无线系统中有很好的实用价值。

The analysis method of a synthetic filter is adopted to give the each value of the circuit elements.The circuitand electromagnetic simulation software are used to synthesize a filter with perfect performance.The ADS2009and HFSS13.0softwares are employed to design the two-port power divider whose passband is2225~2700MHz.The principle analysis and design simulation results show that,in order to make the filter performance better,so long as two reflection zeros and two matching quality factors are preset,the numerical value of each device can be synthesized effectively.The design has certain flexibility,and can set different parameters according to the specification of different filters,which has a high practical value in wireless systems.
