Title: THIN-WALL STRETCHING CAVITY FILTER AND MANUFACTURING METHOD THEREOF
Abstract:
Disclosed are a thin-wall stretching cavity filter and a manufacturing method thereof. The thin-wall stretching cavity filter comprises a cavity wall, resonator posts, tuning screws, and a connector cable assembly, the cavity wall being formed by stretching, the resonant posts being located inside the cavity wall, the tuning screws being connected to the cavity wall, and the connector cable assembly being located outside the cavity wall. The manufacturing method includes stretching a metal material to form a cavity wall, the cavity wall comprising an upper cavity wall and a lower cavity wall; welding the cavity wall with the tuning screws, the resonant posts and the connector cable assembly at a high temperature; and welding the upper cavity wall and the cavity wall at a low temperature. Compared with the prior art, the invention has the advantages of less manufacturing time, short assembly time, light weight, and convenient welding.
