Telecommunications Radio Frequency Filter Housing

RF filters are some of the most important components in the receiver. The main function of the filter is to suppress unwanted signals outside the passband of the filter, and to separate the signal according to its frequency. RF filters can change the amplitude and phase of the sinusoidal waveforms that pass through them, or more simply, RF filters can remove unwanted frequency components from the signal while retaining the required frequency components. This is for RF engineers. An indispensable tool for language. RF filters are designed to process signals in the entire radio spectrum, covering radio, television, wireless communications, scientific research, and military/defense fields. Filters are also components of other RF/microwave equipment (such as duplexers and diplexers) and are used to combine or separate multiple frequency bands. The construction of the filter varies by application, size, cost, and performance

Silver plating is used to prevent corrosion, increase conductivity, reflectivity and aesthetics. It is widely used in the manufacturing industries of electrical appliances, instruments, meters and lighting appliances. For example, when copper or copper alloy parts are plated with silver, they must first be degreasing and rust removed; then pre-plated with thin silver or immersed in a solution of mercury chloride, etc., for mercury treatment, so that the surface of the parts is plated with a Layer mercury film; then the workpiece is used as a cathode, and a pure silver plate is used as an anode, and is immersed in a silver potassium cyanide electrolyte prepared by silver nitrate and potassium cyanide for electroplating. Non-cyanide silver plating is also used in electrical appliances, instrumentation and other industries. The electroplating solution uses thiosulfate, sulfite, thiocyanate, ferrocyanide, etc. In order to prevent the discoloration of the silver coating, post-plating treatments are usually required, mainly including dipping, chemical and electrochemical passivation, plating of precious metals or rare metals, or coating of coatings, etc.

Q1:What the surface treatment ?

A1: For the suface treatment,there are

1. Mechanical surface treatment: sandblasting, shot blasting, polishing, rolling, polishing, brushing, spraying, painting, oiling, etc.
