Agilent/Keysight 137RXC1-3N-50-PDR70

The Agilent/Keysight 137RXC1-3N-50-PDR70 is a WR-137 waveguide to N-type female coaxial adapter configured in right-angle format. It bridges waveguide and coaxial transmission paths across the 5.38 GHz to 8.17 GHz band with 50 ohm nominal impedance, delivering low insertion loss and controlled VSWR for high-frequency RF systems. Built from aluminum with gray painted finish, it withstands 100 Watts CW input power and maintains tight electrical performance in demanding test, measurement, and communication environments.
