摘　　要：介绍了一种平面型波导单脉冲比较器的设计。利用波导混合电桥作为基本结构单元 ,设计了一个X波段单脉冲比较器。通过在波导电桥的输入臂加上四分之一波长变换段 ,将其等效为魔T ,四个这样的等效魔T通过H弯连接可构成双面单脉冲比较器。讨论了一种简易的宽带补相技术 。In this paper, the design of a planar waveguide monopulse comparator is presented. An X band monopulse comparator is designed using waveguide hybrid coupler as a building block. The hybrid coupler is converted to an equivalent of magic Tee, by adding a quarter guide wave length segment to one of the inputs of the coupler. Four such magic Tees are connected using H bends to form a compact two plane monopulse comparator. The phase dispersion of the quarter guide wave length segment can be compensated using a simple method of phase compensation for wide band.
