Description

A New Broadband Cavity Power Divider

technical field

The utility model relates to a novel broadband cavity power splitter, in particular to a high-performance cavity (N type/DIN type) power splitter.

Background technique

At present, in the cavity power divider used in the prior art, there is no insulating material between the cavity and the coaxial rod in the cavity, and the joint is fastened to the cavity with screws, and the structure size of the cavity is limited by the performance of the power divider. Large, the third-order intermodulation is not high, the intermodulation is unstable, and the conventional performance is not good.

Contents of the invention

The purpose of this utility model is to overcome the above-mentioned shortcomings, and to design a new broadband cavity power divider.

In order to achieve the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

A new type of broadband cavity power divider, including a connecting cavity, a coaxial rod, a joint, and an insulator. The coaxial rod is arranged in the cavity and fixed with the cavity through an insulator; one end of the coaxial rod is provided with jack; the joint and the cavity are connected by threads.

As a preferred solution, the connector is a DIN connector, a ferrule is arranged inside the DIN connector, and an interference fit is adopted between the socket and the ferrule.

As a preferred solution, the DIN connector is provided with a boss.

As a preferred solution, the DIN type connector is provided with a sealing ring.

As a preferred solution, the linker is an N-type linker.

The utility model has the advantages and effects that the coaxial rod and the cavity are fixed by an insulator, the connection between the joint and the cavity adopts a screw connection mode, a boss is formed on the joint, and a sealing ring is added, and the DIN type joint socket and pin Interference fit is adopted, and the N-type power divider jack is the N-type connector pin. Therefore, the third-order intermodulation is good and stable, the conventional performance is superior, the structure size is small, and the assembly is simple.
