The 7/16 series name for RF connectors derives from the metric dimensions of the connector interface: 7 mm outer diameter of inner contact, 16 mm inner diameter of outer contact. 7/16 connectors are designed for use in communications systems with power levels of 100 watts per channel. Long popular in Europe, the 7/16 interface has gained acceptance in the US for its ability to operate at elevated power levels.
There are three families of 7/16 DIN connectors: corrugated cable (both Annular and Superflex), standard cable connectors, and custom.
RF coaxial connectors are the most important element in the cable system. Corrugated copper coaxial cables may have the potential to deliver all the performance your system requires, but they are often limited by the performance of the connectors. Amphenol has designed corrugated connectors from the ground up to deliver optimum performance, while retaining ease of installation.
Inter-modulation distortion, a major concern in today's communications systems, is consistently low with these connectors. Typical performance is -125 dBm
(-168 dBc). Amphenol has in-house intermodulation distortion (IMD) measurement capability that gives it the unique ability to understand the effects of connector design elements on IMD generation. This allows Amphenol to design some of the best performing connectors in the industry.
