Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] figure 1 A radio frequency coaxial cable assembly with both ports being waveguide ports is given, which is realized by directly connecting waveguide port connectors at both ends of a radio frequency coaxial cable. Among them, the RF coaxial cable can be flexible, semi-flexible (or semi-soft) or semi-rigid, and its length can be cut as required before assembly, and bent before assembly or during use as required.

[0015] figure 2 The structure of the waveguide port connector connected at both ends of the cable assembly is given, which mainly includes waveguide side plate 1, connecting screw 2, coaxial side plate 3, cable fastening nut 4, cable sleeve 5, socket 6, Jack fastening nut 7, fixing glue 8. The waveguide side plate 1 and the coaxial side plate 3 are connected and fixed together by connecting screws 2. The waveguide side plate 1 is provided ...

Abstract

A waveguide port radio frequency coaxial cable component can realize connection of different waveguide ports or reliable connection of a waveguide port with a radio frequency coaxial port and is suitable for microwave systems with a waveguide port connection. The cable component comprises a terminating waveguide port connector and a radio frequency coaxial cable. The end of the cable component is designed as a standard waveguide port matched with a system. When the cable component is used, a user can directly connect the waveguide port of the cable component with a system waveguide port, so that the cable component is convenient to use. Due to the fact that the coaxial cable is bendable and can satisfy the requirements of optional lengths, connection between waveguide ports at optional positions can be realized. Compared with the original manner that the radio frequency coaxial cable component is matched with a waveguide coaxial converter, part number introduced to the system is reduced, two port sections with discontinuous impedance are omitted, system performance and reliability are improved, and high feasibility and practicability are achieved.

Description

technical field [0001] The invention relates to a cable assembly, in particular to a radio frequency coaxial cable assembly whose port is a waveguide port. Background technique [0002] Waveguide coaxial conversion devices are widely used in microwave circuits, and are important passive devices in radar equipment, precision guidance and microwave test systems, especially in the millimeter wave band and where there are relatively high requirements for transmission power, the waveguide coaxial structure is the most efficient conversion device. [0003] In a microwave transmission system, waveguide connections are usually used between different waveguide interfaces. However, the processing precision of waveguides is high and is limited by the number of turns. Therefore, it is difficult to adapt to complex space structures. Coaxial cable assemblies are often used for transition switching. Usually, two A waveguide-to-coaxial conversion connector and an RF coaxial cable assembly ...
