Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and in particular relates to a high-suppression filter. Background Art

[0002] High-rejection filters are specially designed filters that allow signals of certain frequencies to pass while significantly suppressing or blocking signals of other frequencies. These filters are widely used in signal processing, for example, in the front-end preselection section of superheterodyne receivers, where they achieve high out-of-band rejection of intermediate frequencies, image frequencies, and local oscillator (LO) reverse frequencies. Many existing filters have their internal circuit boards mounted directly to the inner wall of the enclosure module. This makes them susceptible to damage from external forces and provides poor mounting stability. Furthermore, existing filters lack effective heat dissipation, making them susceptible to damage due to heating during operation.

[0003] Therefore, further improvements are made to the above problems. Utility Model Content
