TYPE NAMING RULES OF RF COAXIAL CONNECTOR Type Naming The type of RF connector is made up of main symbol and structural symbol. Part with “-“. Main Symbol Main symbol of RF connector use international universal main symbol. The naming rules of different structural product concretely are prescribed by detailed criterion. Structural Symbol Structural symbol of RF connector is in table 1:characteristics Table 1 Structure Format Classification & Symbol

Sample for model composing of RE connector Example 1: MCB-JW3 Means type MCB curly RF plug. inside conductor is pin, match SFF-50-3-1, RG58/U RF coaxial cable. Example 2: BNC-50KWE Means type BNC right angle RF socket which is welded in PCB and 50 resistance.
Naming and composing example for adaptor & resistance transformer Model of adaptor & resistance transformer base on that of plug or socket. Main symbol of adaptor model is marked with connector-main-symbol (inter-series) or factionary from (between series). Example 1: N-50JK Means type N-50jk series adaptor. One port is positive contact part, another is negative contact part. Example 2: TNC/SMA-50JK Means the adaptor which one port is TNC positive contact part, another port is SMA negative contact part, resistance is 50Ω.
Denoting model of impedance transformer Example: N-50J/75K Means type N impedance transformer contact which one port is 50 positive contact part, another port is 75Ω negative contact part. |
