Abstract

The multi-cavity UHF dielectric filter with several connected dielectric blocks is one kind of electronic device. The UHF dielectric filter consists of printed circuit board, dielectric filter and shielding casing. The dielectric filter is welded to the printed circuit board, and the shielding casing has its upper plane welded on ground electrode, front side bottom edge welded to the ground of the printed circuit board, and rectangular through holes. Owing to the shielding casing, the UHF dielectric filter has high interference immunity and easy electric performance regulation.

Description

Technical field: [0001] The ultra-high frequency conjoined multi-cavity patch dielectric filter of the present invention is an electronic component, which can adjust the electrical performance of its ultra-high frequency filter, and can shield interference signals, and is directly mounted on a printed circuit board. It belongs to A multi-cavity patch filter composed of multiple dielectric blocks. Background technique: [0002] After the input signal passes through the filter circuit, the frequency components that do not need to pass in the signal can be filtered out, and the dielectric filter is a passive filter circuit, which is composed of passive filter components such as resistors, capacitors, and inductors. The values ​​of these passive components and their circuit connections determine the resonant frequency. For this reason, band-pass filters, high-pass and low-pass filters, and band-stop filters can be designed. [0003] If each dielectric block is connected in seri...
