N Type Receptacle for High-Frequency and High-Voltage RF Paths
The 000-49000-SRFX: This connector sits in the standard N Type family, a 50 Ohm interface widely used in base stations, antenna feeds, microwave test equipment, and industrial RF systems. The 50 Ohm impedance is held through a PTFE dielectric, and the connector is rated to 11 GHz, covering L-band through X-band frequencies. A 1500 V voltage rating sets it apart from typical N Type connectors, which usually top out at 1000 V, making this part suited for high-power RF or pulsed signal paths where voltage standoff is the limiting factor.
The 11 GHz maximum frequency is the practical ceiling for this connector; above that, the N Type interface geometry starts to support higher-order modes that degrade VSWR. For a clean 50 Ohm path up to 11 GHz, the solder cup termination must be executed with consistent center-conductor standoff and minimal solder voiding. The 500 mating cycles rating, backed by gold-over-nickel plating on the center contact, means this receptacle can survive years of field reconnections in test racks or antenna line-ups before contact wear becomes a concern. The weatherproof ingress protection (IP-rated per the manufacturer's definition) allows outdoor panel mounting without a separate boot or gasket, as long as the mating plug is also weatherproof.
Mounting and Termination: Panel Flange and Solder Cup
The shield is terminated to the chassis or cable braid through the solder cup on the outer conductor — a reliable method for high-power or high-vibration installations where a crimp might loosen. The center contact uses a separate solder cup, requiring the cable center conductor to be tinned and inserted before soldering.
