Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a high-frequency filter used for a power amplifier. Background Art

[0002] High-frequency common-mode filters usually use ferrite cores, two-wire parallel winding, low differential-mode noise signal suppression interference source, difficult to deform in high-speed signals, good noise suppression countermeasures, high common-mode noise suppression and low differential-mode noise signal suppression. The design of common-mode filters is relatively simple, including common-mode capacitors, unbalanced transformers or common-mode inductors. When using high-frequency common-mode filters, in order to make their installation easier, it is also convenient for subsequent disassembly and maintenance, as well as for the implementation of stable protection.

[0003] A high-frequency filter with patent application number 202320057874.5 is disclosed. A locking assembly is provided, and a locking ring is sleeved on the outside of a fixed shell. When the terminal block is threadedly connected to the conductive seat, a block fixedly connected to the end of the locking rod is fixed inside the positioning hole. The locking rod is subjected to the elastic force of a spring to prevent the terminal block and the conductive seat from loosening, thereby solving the problem in the prior art that the device is easily loosened by vibration and affects the anti-interference ability. However, the above-mentioned case does not have the function of opening and repairing the high-frequency filter. The existing one is usually an integrated filter that cannot be opened and repaired. As a result, when the internal parts and circuits are damaged, a new filter needs to be replaced for use. This not only wastes material use, but also affects the working efficiency of the filter. At the same time, the filter in the above-mentioned case does not have a sealing effect, which will cause air leakage during use, affecting the use of the power line, and greatly reducing the service life of the equipment.
