一、引言1.1 本报告是同学参加教研组生产劳动中对我院生产之波导元件——定向藕合器测试之结果。报告中对定向耦合器之主要参量:过渡衰减及方向性均进行了测试。并对一组耦合孔径不同的定向耦合器进行测试,得到耦合孔径与过渡衰减间之关系曲线。报告中介绍了一些对定向耦合器参量测试的方法,并利用所述方法测试了我们生产之定向耦合器31个 I. INTRODUCTION 1.1 This report is the result of the test of directional coupler conducted by the students participating in the production labors of our research group on the waveguide components produced in our hospital. The report on the main parameters of the directional coupler: transition attenuation and directionality were tested. A series of directional couplers with different coupling apertures were tested and the relationship between the coupling aperture and the transition attenuation was obtained. The report describes some methods of parametric testing of directional couplers and uses the method to test the number of directional couplers we produce
