Problems solved by technology

However, in the actual production process of this technology, the design is only suitable for lower frequency bands, for example, 6G and 7GHz frequency bands for point-to-point communication
In the high-frequency band, the design has a large volume and the risk of information leakage
Moreover, when the above solution is applied in a higher frequency band, the yield rate of the product is not high, and the production cost still has the problem of high

Embodiment Construction

[0031] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] figure 1 It is an example of a waveguide coupler provided by the present invention. The coupler is suitable for higher frequencies, and is mainly used in the design and production of 11GHz--42GHz microwave couplers in microwave point-to-point communication. Its structure mainly includes: shell, polarizer, waveguide. refer to figure 2 As shown, the waveguide includes two connected to the first polarizer 11, the second polarizer 22 and the antenna polarizer 33 respectively, and a coupling window 4 is provided between the waveguides for transmitting the The electromagnetic wave is coupled into another waveguide, and the size of the coupling window and the di...

Abstract

A waveguide coupler has a housing divided into a lower housing and an upper cover along an E plane of the waveguide, and a cavity accommodating the upper cover is provided in the lower housing. The end of the cavity is provided with at least one protrusion for abutting with the upper cover. Thus, the waveguide coupler provided by the invention can ensure the bottom surface and the end surface of the cavity, and the two mutually perpendicular surfaces are closely adhered to the upper cover due to the extrusion of the protrusion. Thus, the waveguide coupler provided by the present invention doesnot require an additional fixing structure, the number of parts thereof is only three, and since both the bottom surface and the end surface of the cavity can be directly and tightly attached to theupper cover, the present invention can be directly sealed by glue pouring. Therefore, the coupler of the present invention is more convenient to assemble, has less signal leakage, and has high reliability and lower component cost.

Description

technical field [0001] The invention relates to the field of communication, in particular to a microwave device. Background technique [0002] Microwave waveguide couplers are widely used in microwave point-to-point communication systems. Two ODUs (Outdoor unit, outdoor communication transceiver unit) can work at the same time by using the microwave coupler, realizing the hot backup function of the communication system. Its bracket is generally used as a hanger for antennas and ODUs. In order to facilitate the installation of ODUs and antennas in various occasions, a polarized design is often required. At present, the microwave coupler technology with frame design is very mature, and there are many mature products at home and abroad. For example, ZL201310505625.9 provides a framed microwave coupler. [0003] Due to the huge shipments of microwave couplers, the cost of their products is a very critical consideration. How to reduce the cost under the premise of ensuring p...
