In addition, the embodiment of the invention also discloses a cavity filter and a communication apparatus using the cavity filter. The embodiment of the invention discloses a novel way of thinking for surface treatment methods for filter cavities, can enhance the corrosion resistance and abrasion resistance, and can lower the processing cost.

Description

【Technical field】 [0001] The invention relates to cavity filter technology in the communication field, in particular to a surface treatment method for a filter cavity, a cavity filter and communication equipment. 【Background technique】 [0002] The cavity filter is widely used in the communication field as a frequency selection device. Due to the special requirements of the cavity filter on the conductivity of the cavity, the surface of the cavity must be electroplated. [0003] Electroplating is a process of plating a thin layer of other metals or alloys on some metal surfaces by using the principle of electrolysis. Electroplating can prevent corrosion, improve wear resistance, conductivity, reflectivity and enhance aesthetics. [0004] The cavity filter mainly includes a cavity and connecting components arranged on the side of the cavity. In the prior art, in order to improve the performance of the cavity filter while reducing the cost, a new cavity structure is to integr...
