Abstract描述了一款宽带脊过渡正交模耦合器,该正交模耦合器中心频率为40 GHz,相对带宽50%,拟应用于射电望远镜Q波段接收机系统。该正交模耦合器由双脊过渡-分支接头、Y型接头、E型弯头组成,其结构紧凑,降低了加工装配误差对电气性能的影响。对该正交模耦合器实际加工后进行测试,其Y型接头输出口回波损耗≤-22.7 dB,直臂输出口回波损耗≤-21.0 dB,Y型接头输出口-直臂输出口隔离度≤-45.6 dB。实测结果表明该正交模耦合器反射损耗和隔离度与仿真结果的曲线变化趋势基本吻合,在实际工作频带30~50 GHz范围内可以满足射电天文观测需求。
Other AbstractThis paper describes a wideband orthomode transducer (OMT) based on the ridged waveguide connection, the center frequency of OMT is 40 GHz, relative bandwidth is 50%. The transducer is aimed to work in Q-band receiver system in radio telescope. This OMT is composed of dual ridged waveguide connection joint, Y type joint and E type elbow, the structure of OMT is compact, and the influence of processing and assembling errors on the electrical performance is reduced. After testing the actual machining of the OMT, the reflection loss of Y type joint output S11≤−22.7dB, the reflection loss of direct arm output ≤−21.0dB, and the isolation between Y type joint output and direct arm output ≤−43.4dB. The trend of curve change between actual measure and simulation result is very similar, and this OMT can satisfy the requirements of radio astronomic observation in (30~50) GHz bandwidth.
