摘要
功率分配器是一种常用的无源器件,随着通信设备小型化的要求越来越高,无源器件的体积成为其发展瓶颈。本文基于Wilkinson功率分配器的结构,采用LC阻抗变换节取代传统电路的λ/4传输线,减小功分器体积。经ADS软件进行仿真验证,在108M~174MHz的带宽内功率分配损耗≤0.2d B,隔离度≥20dB,输入输出端口回波损耗≤-20d B,通过采用高耐压高Q电容器及电感器,实现了Wilkinson功分器低插损、小体积、电路性能一致的优点,同时实现了对大功率信号的分配。
Power divider is a general passive component. With the development of communication devices,it is necessary to use components in smaller size,which is the bottleneck in this field.Based on the theory of Wilkinson power divider,this paper presents the design of a 1:2 power divider which is using LC impedance transforming instead of traditional λ/4 transmission line. The ADS simulation result of the power divider shows its insertion loss≤0.2 d B, isolation>20d B and the return loss≤-20 d B in the bandwidth of 108~174MHz. By using the high power high Q capacitors and inductors,the power divider has advantages of low insertion loss,small size, consistent electric performance and the distribution of the high power RF signals.
