N (or N-Type) flange connectors are used within high performance low-band radio communications systems, such as in aerospace, radar, 4G cellular, and broadcast.

This N female connector is used to terminate coaxial cable types onto a panel where both the inner conductor and outer braid are soldered accordingly. The female connector body has a flange design with four mounting holes.

As a low-PIM design the connector uses ternary alloys to achieve very low VSWR under 3 GHz, and a modest < 1.3:1 VSWR up to 6 GHz.

This N Female coaxial connector is used in high performance and general-precision systems up to 6 GHz. Termination of flange connectors particularly those operating towards the upper frequency limit must be made with great care and precision.
