N Coaxial Connectors
N Coaxial Connectors
The Amphenol N connectors with screw coupling are fully interchangeable with N connectors made
to the MIL-C-39012 specification. Designed for use in all systems where very good R.F. and
mechanical performance is critical, whether it be at low or high frequencies.
Plating for intermodulation problems
Intermodulation problems have long been a serious concern for the telecommunications market.
The elimination of all nickel plating on N series connectors has gone a long way to solve this
problem. Amphenol offers both silver-plated (no nickel undercoat on body or under 30 µ" gold
center contact) and Nexcote-plated connectors. Nexcote is our trade name for the popular white
bronze plating, and is fully compatible with all other commercial tri-alloy platings on the market.
