The 7/16 series name drives from the metric dimensions of the
connector interface: 7mm OD of inner contact, 16 mm ID 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 U.S.
for its ability to operate at elevated power levels.
Deutsh Industries Norm (DIN) is an acronym for German standards
that apply to 7/16 connectors and are gaining acceptance worldwide.
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 have the potential to
deliver all the performance your system requires, but they are
often limited by the performance of the connectors. Corrugated
connectors have been designed 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's in-house IMD measurement capability
gives us the unique ability to understand the effects of connector
design elements on IMD generation so that we can design the best
performing connectors in the industry.
