一种串联式功分器设计

功分器是微波器件中的基本器件，常见的功分器都是用并联电路来实现，由并联电路的特点可知，当功分比较大时，功分器将存在高阻线，这就增加了加工难度，同时也增大功分器的插损，从而限制了并联式功分器在某些领域的使用。文中提出了一种串联式功分器结构设计，给出了等效电路，并对其进行仿真设计，仿真结果表明此方法是有效的。与Wilkinson功分器相比，串联式功分器工程上能够实现较大的功分比，输出相位差为180°，在超宽带巴仑和平面魔T等方面具有潜在的应用价值。

Design of a Serial Circuit Power Divider

： Power divider is a general microwave device. The traditional power divider is realized by use of parallel circuit. So that its application may be limited in specific domain. In this paper,a serial circuit power divider prototype is presented and its equivalent circuit is introduced. Simulation was conducted using HFSS to verify the design. An unequal power with higher division ratios and 180° out of phase can be obtained easily by means of the proposed divider. The divider should play an important role in broadband Balun and coplanar magic T applications.
