Abstract
The invention discloses an orthogonal mode coupler with a frame. The cavity of the inner core of the orthogonal mode coupler is integrated with the frame as one piece. The closed side of the cavity is connected with a polarizer and the opened side of the cavity is matched with a cover plate to form the inner core of the orthogonal mode coupler. The cover plate is integrated with another polarizer. The front end of the cavity is connected to a public port. The orthogonal mode coupler of the invention consists of 4 components, wherein a cavity and a bracket are designed as one piece. In this way, not only the number of the parts of a product is reduced, but also the product strength is greatly optimized. Moreover, the load capacity, the wind resistance and other performances of the entire product are improved. One polarizer and one cover plate are integrated into a single part. At the same time, the branch of the orthogonal mode coupler in the vertical polarization direction is designed to rotate at 90 degrees, so that the E surface subdivision is enabled in both the vertical polarization direction and the horizontal polarization direction. Therefore, the insertion loss of the product is greatly reduced. The contact portions of the cover plate and the cavity at the public port are machined at a certain inclination, so that the cover plate and the cavity can be tightly attached and assembled together in a plurality of directions.
