Embodiment Construction

[0014] A coaxial microstrip conversion device includes: a coaxial connector 1 and a box body 2, and also includes: a solder ring 6, a cavity matching groove 7 and a gold band ring 8.

[0015] The input and output of the RF component are connected to external signals through the coaxial connector 1. There are coaxial connector mounting holes 3, cavity matching grooves 7 and solder rings 6 at the input and output positions of the RF component box body 2. The position of the mounting hole is the input of the RF component. At the output, the shape of the mounting hole matches the coaxial connector 1 used; the cavity matching groove 7 is a ring concentric with the coaxial mounting hole; the solder ring 6 is directly above the coaxial connector mounting hole 3 on the box body 2, and the shape It is the same as the installation hole 3 of the coaxial connector, and is 1mm larger than the installation hole 3 of the coaxial connector. A microstrip substrate installation surface 5 is pro...

Abstract

The present invention discloses a coaxial microstrip transition device. The device comprises a coaxial joint and a box body (2), and also comprises a solder ring, a cavity matching groove and a metalstrip ring. The solder ring makes sealing and consistence of welding of the coaxial joint better, and make grounding of microwave signals better; the welding technology mode of the metal strip ring ensures batch consistence of performances of a transition device and performs interaction with the cavity matching groove, and the matching of the microwave signals is better to achieve high-efficiencyenergy transition. After the coaxial joint is fixed on the box body through a coaxial joint installation hole (3), and the coaxial joint is welded with the box body through the solder ring so that thesealing of the combination is ensured and the coaxial joint and the housing is better connected to facilitate transmission of the microwave signals.

Description

technical field [0001] The invention relates to a microstrip conversion device, in particular to a coaxial microstrip conversion device. Background technique [0002] For highly integrated RF components, the external interface is generally in the form of coaxial SMA, SMP, etc., and the components are all RF components and chips in the form of microstrip, so the coaxial microstrip conversion device is an essential component of RF components part. In the past, coaxial connectors in the form of SMA, SMP, etc. were usually used, fixed or welded on the box body with screws, and then the inner conductor was directly welded on the microstrip substrate, and the external RF input signal was connected to the input end of the RF component through the coaxial connector. The output end of the radio frequency component is used as the output end of the radio frequency component after passing through the coaxial connector. The high-frequency performance of this method is poor, the energy ...
