Embodiment Construction

[0024] For ease of understanding, the specific structure and operation of the present invention will be further described herein:

[0025] Specific configurations of the present invention refer to 1-5, mainly including an orthogonal mode coupler, and filter 20. The orthogonal mode coupler includes a circular wave guide 11, a square waveguide 12, an uplink rectangular waveguide 13, a downlink rectangular waveguide 14. The filter 20 is connected to the downlink rectangular waveguide 14 and is indirectly coupled to the orthogonal die coupler by the coupling window 15 at the downward rectangular waveguide 14.

[0026] like image 3 As shown, the square waveguide 12 is a metal waveguide having a square cross section, and the front end surface of the square waveguide section is closed and the rear end face is closed, and the first oblique section A and the third oblique section C are disposed at the rear end surface. The coupling window 15 is disposed at the side of the square waveguide ...

Abstract

The invention belongs to the technical field of mobile satellite communication, and in particular relates to a duplex component for mobile satellite communication. The duplex component includes an orthogonal mode coupler composed of at least a circular waveguide, a square waveguide, an uplink rectangular waveguide, and a downlink rectangular waveguide. The other end of the downlink rectangular waveguide, where the coupling window is oppositely arranged, is a "U"-shaped extension with a filter The uplink rectangular waveguide is arranged at the other end of the uplink rectangular waveguide opposite to the square waveguide, forming a ninety-degree bent structure between the two, and its bent surface is parallel to the plane of the "U"-shaped structure of the filter; square A first beveled surface and a third beveled surface are provided at the rear end of the waveguide; a second beveled surface is arranged at the outer bend of the "L"-shaped bending structure. The invention has good structural stability, small size and easy installation, and is especially suitable for installation in mobile communication equipment with a small internal space below 0.3 meters.

Description

Technical field [0001] The present invention belongs to the field of mobile satellite communication, and more particularly to a moving medium-pass satellite communication duplex assembly applied to a moving in a dynamic in-units such as a size of 0.3 meters or less. Background technique [0002] The duplex assembly is also moving in the mobile satellite communication device, and is often connected to the airfoil source as an antenna feeder, which is a key member that transmits and receives a shared bipolarization antenna. The most important role of the duplex component is to isolate the electromagnetic wave signal reflected by the reflective surface antenna, and the signal is polarized separately. In special applications, there is a need to use small-sized moving tongue devices, especially when there is a size of less than 0.3 meters or less, due to the limit of internal structural dimensions, there is an urgent duplex component. Traditional duplex components tend to have large s...
