Problems solved by technology

[0003] In the coaxial adapter, it is necessary to use a supporting medium to fix the inner ferrule and the outer shell to form a stable whole, but the relative permittivity will change due to the supporting medium in it, resulting in discontinuity of impedance , while traditional adapters generally adopt a double-supported dielectric structure, which often results in a larger VSWR
The single insulating medium adapter disclosed in the patent No. CN105514794A does not realize the conversion of different interfaces

Abstract

The invention relates to the technical field of microwave electronic equipment interconnection, and discloses a single-support medium coaxial adapter with capacitive compensation. The single-support medium coaxial adapter is characterized by comprising an SMA jack shell (1), an SMPM pin shell (2) and a stub assembly, the stub assembly comprises an inner stub (3) and an insulation support medium (4) which are coaxially arranged, the insulation support medium (4) is fixed on the outer peripheral surface of the inner plug (3), the plug assembly is inserted into the SMA jack shell (1) from one endfar away from the insulation support medium (4), a first step structure (11) is arranged in the SMA jack shell (1), a second step structure (21) is arranged in the SMPM pin shell (2), and when the SMA jack shell (1) and the SMPM pin shell (2) are in an inserted state, the SMPM pin shell (2) and the SMA jack shell (1) are connected through threads, and the two ends of the insulation supporting medium (4) abut against the first step structure (11) and the second step structure (21) respectively.

Description

technical field [0001] The invention relates to the technical field of interconnection of microwave electronic equipment, in particular to a single-medium coaxial adapter from an SMA to an SMPM interface. Background technique [0002] The coaxial adapter is a commonly used microwave component and one of the most basic components for the interconnection of microwave electronic equipment. With the current miniaturization trend of the whole machine system, the RF coaxial connector and the RF coaxial adapter are also developing towards the trend of miniaturization and high frequency, so the application of SMA and SMPM interface connectors is becoming more and more extensive. At the same time, the requirements for the adapter are getting higher and higher, so it is necessary to design the adapter for SMA / SMPM. [0003] In the coaxial adapter, it is necessary to use a supporting medium to fix the inner ferrule and the outer shell to form a stable whole, but the relative permittiv...
