Abstract

The invention discloses a high-power radio frequency filter, which comprises a cavity, a cover plate, a resonance column connected with the cover plate and arranged in the cavity, and a tuning screw arranged in the resonance column and penetrating out of the cover plate, the tuning screw penetrates through the cover plate to be connected with an external circuit board, a heat dissipation device isarranged on the cavity, the heat dissipation device comprises a heat dissipation shell forming a cavity, the inner surface and the outer surface of the heat dissipation shell are each coated with a heat conduction film layer, and the heat conduction coefficient of each heat conduction film layer is not smaller than 230 W / mK. The high-power radio frequency filter solves the problem that a radio frequency filter in the prior art is poor in heat dissipation effect and unstable in work.

Description

technical field [0001] The invention belongs to the field of filters, and more specifically relates to a high-power radio frequency filter. Background technique [0002] When filters, especially radio frequency filters, are applied to high-power electrical equipment, it is easy to cause the radio frequency filter to lose its stable working state due to the high temperature environment, so that the radio frequency filter cannot work well during the use of high-power electrical equipment. Effectively filter the frequency point of a specific frequency in the power line or frequencies other than this frequency point to obtain a power signal of a specific frequency or eliminate a power signal of a specific frequency. Contents of the invention [0003] The purpose of the present invention is to provide a high-power radio frequency filter to solve the problem of poor heat dissipation of the radio frequency filter in the prior art, resulting in unstable operation. [0004] The te...
