MCX,miniature connectors based on the CECC 22220 standard. It uses identical inner contact and insulator dimensions as the SMB, it is also called VAA. MCX allows high density use in a small area, giving a space saving of 30% to 40%, when Compared with SMB connectors. Because of careful precision manufacturing along with tight quality control at each and every production stage and its very small dimensions, the connectors of MCX series can be used up to a frequency of 6GHz with a snap-on connector design. All these qualities make these connectors particularly suitable on new developments for both civil and military radio applications.
