AD-NJBNCP-1 is a 75 Ohm RF test adapter that provides a Type N jack to BNC plug interface, designed for controlled laboratory environments. It features a frequency range of DC to 12 GHz with VSWR (return loss) of -20 dB minimum from DC to 6 GHz and -15 dB minimum from 6 to 12 GHz. The adapter is constructed with a brass body with nickel plating, phosphor bronze contacts with gold plating, and a natural PTFE insulator. It offers a dielectric withstanding voltage of 500 VRMS minimum and durability of 500 mating cycles minimum. The interfaces conform to MIL-STD-348 specifications for both Type N and BNC series connectors, making it ideal for precision RF testing and measurement applications in laboratory settings.
