摘要

提出了一种以低通微带滤波器代替传统传输线的小型化支路耦合器。采用5阶、7阶和9阶低通滤波器对所提出的耦合器进行设计。这样做是为了在微带实现中实现紧凑的电路布局。使用微带技术设计并实现了这些结构的原型，工作频率为2ghz。

Realization of miniaturized branch-line coupler using lowpass microstrip filters

A miniaturized branch-line coupler based on lowpass microstrip filters instead of conventional transmission lines is presented in this paper. The design of proposed couplers is performed using lowpass filter of 5th, 7th and 9th order. This is done to achieve a compact circuit layout in microstrip implementation. Prototypes with these proposed structures, operating at 2 GHz frequency, have been designed and implemented using microstrip technology.
