Abstract本发明涉及一种Q波段脊过渡正交模耦合器,该耦合器为宽带双脊过渡‑分支合成结构,中心频率40GHz,相对带宽50%,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、第一E型弯头、第二E型弯头、第一侧壁分支口、第二侧壁分支口、双脊、双脊过渡段、匹配钉、电感膜片、第一90度弯头、第二90度弯头和阻抗变换段组成,双脊过渡‑分支接头主要用于分离两个正交极化信号,其中直通道的双脊过渡采用了三个台阶,侧壁分支通道引入匹配钉和电感膜片;Y型接头用于将双脊过渡‑分支接头输出的两路水平极化信号合成一路信号;E型弯头用于连接双脊过渡‑分支接头和Y型接头。该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,以满足射电天文观测需求。
Other AbstractThe invention relates to a Q-waveband ridge transition ortho-mode transducer. The coupler is of a broadband double-ridge transition-branch synthetic structure, has a center frequency of 40GHz and relative bandwidth of 50% and is used for a radio telescope Q-waveband receiver system. The ortho-mode transducer is composed of a double-ridge transition-branch joint, a Y-shaped joint, a first E-shaped bend, a second E-shaped bend, a first sidewall branch port, a second sidewall branch port, double ridges, a double-ridge transition segment, a coupling screw, an inductive diaphragm, a first 90-degree bend, a second 90-degree bend and an impedance transformation segment, wherein the double-ridge transition-branch joint is mainly used for separating two orthogonally polarized signals, double-ridge transition in a straight channel employs three steps, and a sidewall branch channel introduces the coupling screw and the inductive diaphragm; the Y-shaped joint is used for combining two horizontally polarized signals output by the double-ridge transition-branch joint into one signal; and the E-shaped bends are used for connecting the double-ridge transition-branch joint with the Y-shaped joint. The actual measurement results of reflection loss and isolation of the coupler are basically consistent with simulation results, and thus the radio astronomical observation demand is satisfied.
