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.
