IP65 Female N Type RF Connector DC 11GHz 5000 Megohms Insulation Resistance
Product Description
Originally, the connector was designed to carry signals at frequencies up to 1 GHz in military applications, but today's common Type N easily handles frequencies up to 11 GHz. More recent precision enhancements to the design by Julius Botka at Hewlett Packard have pushed this to 18 GHz. The male connector is hand-tightened (though versions with a hex nut are also available) and has an air gap between the center and outer conductors. The coupling has a 5/8-24 thread.
The center coaxial contacts are identical to TNC and BNC connectors. Amphenol suggests tightening to a torque of 15 inch-pounds (1.7 N·m), while Andrew Corporation suggest 20 inch-pounds (2.3 N·m) for their hex nut variant. As torque limit depends only on thread quality and cleanliness, whereas the main operational requirement is good RF contact without significant steps or gaps, these values should be seen as indicative rather than critical.
