N-Type Connectors

N-Type Connectors

n type
N-Type connectors are designed to satisfy the need for a durable, weatherproof, medium-size RF connector with consistent performance which includes models that support up to 18 GHz.

Amphenol RF’s N-Type connector features a threaded coupling mechanism and is fully interchangeable with N-Type connectors made to the MIL-C-39012 specification. These connectors are used in all systems where excellent RF and mechanical performance is critical.
