Embodiment Construction

[0024] For ease of understanding, the specific structure and working process of the present invention are further described below in conjunction with the drawings:

[0025] The specific structure of the present invention is shown in reference to 1-5, which mainly includes an orthogonal mode coupler and a filter 20 . The orthogonal mode coupler includes a circular waveguide 11 , a square waveguide 12 , an uplink rectangular waveguide 13 , and a downlink rectangular waveguide 14 . The end of the filter 20 is connected to the downlink rectangular waveguide 14 and indirectly coupled to the orthogonal mode coupler through the coupling window 15 at the downlink rectangular waveguide 14 .

[0026] Such as image 3 As shown, the square waveguide 12 is a metal waveguide with a square cross section. The front end face of the square waveguide 12 is connected to the circular waveguide 11 and the rear end face is closed, and the first beveled plane a and the third beveled plane c are arra...

Abstract

The invention belongs to the technical field of mobile satellite communication, and specifically relates to a mobile satellite communication duplex component. The duplex component comprises an orthogonal mode coupler which is at least composed of a circular waveguide, a square waveguide, an uplink rectangular waveguide and a downlink rectangular waveguide. A U-shaped filter stretches from the other end of the downlink rectangular waveguide opposite to the end at which a coupling window. An uplink channel rectangular waveguide is arranged at the other end of the uplink rectangular waveguide opposite to the end which is connected with the square waveguide. A 90-degree bending structure is formed between the uplink channel rectangular waveguide and the uplink rectangular waveguide. The bending plane of the bending structure is parallel to the plane of the U-shaped structure of the filter. The rear end of the square waveguide is equipped with a first diagonal plane and a third diagonal plane. A second diagonal plane is arranged at the outer bending part of an L-shaped bending structure. The duplex component is high in structure stability and small in body size, is easy to place and is especially suitable for being mounted in the mobile communication equipment which is shorter than 0.3 meter and has a relatively small internal space.

Description

technical field [0001] The invention belongs to the technical field of mobile satellite communication, and in particular relates to a duplex component for mobile satellite communication which is applied to miniaturized mobile communication equipment with a size below 0.3 meters. Background technique [0002] In the mobile satellite communication equipment, that is, the mobile communication equipment, the duplex component is often used as an antenna feeder to connect with the feed source, and it is a key component for transmitting and receiving a shared dual-polarized antenna. The main function of the duplex component is to separate the electromagnetic wave signal reflected by the reflector antenna, and to separate the polarization of the signal. In special applications, it is necessary to use small-sized mobile communication equipment, especially when the size of the mobile communication is less than 0.3 meters, due to the limited size of the internal structure of the mobile...
