Abstract本发明涉及提供一种Q波段隔板型正交模耦合器,该正交模耦合器为宽带隔板?分支合成型,中心频率40GHz,相对带宽50%,应用于射电望远镜Q波段接收机系统。该正交模耦合器是由隔板?分支接头、Y型接头、第一π型弯头、第二π型弯头、第一侧壁分支口、第二侧壁分支口、隔板、金属销钉、匹配钉、方矩过渡、第一90度弯头、第二90度弯头、阻抗变换段、H面弯头组成,隔板?分支接头主要用于分离两个正交极化信号,Y型接头用于将隔板?分支接头输出的两路水平极化信号合成一路信号,π型弯头用于连接隔板?分支接头和Y型接头,该正交模耦合器反射损耗和隔离度的实测结果与仿真结果基本吻合,可以满足射电天文观测需求。
Other AbstractThe invention relates to a Q-band partition board type orthogonal-mode coupler, which is of a broadband partition board and branch combined type, has center frequency of 40 GHz and relative bandwidth of 50%, and is applied to a radio telescope Q-band receiver system. The orthogonal-mode coupler is composed of a partition board-branch connector, a Y-shaped connector, a first n-shaped elbow, a second n-shaped elbow, a first side wall branch port, a second side wall branch port, a partition board, metal pins, matching nails, a square matrix transition piece, a first 90-degree elbow, a second 90-degree elbow, an impedance transformation section and an H-plane elbow, wherein the partition board-branch connector is used for separating two orthogonal polarization signals, the Y-shaped connector is used for synthesizing two paths of horizontal polarization signals output by the partition board-branch connector into one path of signal, and the n-shaped elbows are used for connecting the partition board-branch connector and the Y-shaped connector. The actual measurement results of reflection loss and isolation degree of the Q-band partition board type orthogonal-mode coupler approximately agree with the simulation results, thereby being capable of satisfying the needs of radio astronomical observation.
