摘要
文章详细描述了一种特殊结构的宽带3dB电桥的制作过程和预算，提出了一种近似带状线的宽带3dB电桥设计方案。该方案可使电桥方向性更好、制作工艺更加简便，其带宽可达到800～2500MHz，可以承受较大的功率容量，体积小，新式结构使其实现了低插损、高方向性和宽频带，并且易生产、易调试。
This paper describes in detail the manufacturing process of and budget for a specially structured 3 dB hybrid, and presents a design scheme for the approximately stripline-structured 3 dB hybrid so as to make it better directional and easier to manufacture. It operates from 800 MHz to 2 500 MHz and supports fairly large power capacity. Thanks to its new structure, it has smaller volume, lower insertion loss, higher directionality and broader bandwidth, and is easier to manufacture and test.
