H+S connectors
N connectors
N connectors are available with 50 Ω and 75 Ω impedance. The frequency range extends to 18 GHz, depeding on the connector and cable type. The screw-type coupling mechanism provides a sturdy and reliable connection.
The N connectors are available for flexible cables, for semi-rigid cables and for corrugated copper tube cables.
Compatibility
Inner conductors of N 75 Ω connectors have a smaller diame- ter than those of the 50 Ω version. Therefore 50 Ω and 75 Ω connectors must not be mated with each other.

SMA - coaxial connectors
Description
SMA connectors are precision connectors for microwave applications up to 18 GHz. The extended frequency version operates with exellent return loss performance up to 26.5 GHz. There is a huge variety of application for HUBER + SUHNRT SMA connectors, as in telecom, test+measurement, instruments, avionics, etc.
