About the naming method of the RF connector

RF connector is referred to as: RF connector, usually considered to be attached to the cable Or an element mounted on the instrument as an electrical connection or separate component of the transmission line. It is a mechatronic product. Simply speaking, it mainly serves as a bridge.

First, RF Connector Naming Method

The model of the universal RF connector consists of two parts: the main code and the structure code, separated by a dash "-". Other conditions to be specified may be specified in the detailed specification and separated by a dash line and a structural code.
