摘要

报道了一种t型和pi型等效电路相结合，保持主线特性阻抗为50Ω的混合型支路耦合器。新的支路耦合器只包含电容和开路存根。设计了两支路和三支路样机，并进行了仿真和测量。与原电路相比，尺寸减小了40%。仿真结果与实验结果吻合较好，在目标频率范围内。

Mixed type branch line coupler designs

A mixed type branch line coupler combining T-type and pi-type equivalent circuits and keeping main lines characteristic impedance at 50Ω is reported. The new branch line coupler contains only capacitors and open stubs. Two prototypes of two and three branches are designed, simulated and measured. The size reduction reached 40% comparing with the original circuits. The simulated and experimental results show a good agreement within the frequency of interest.
