RF Waveguide Termination, WR-10, UG-387/U, 0.5 W, 75-110 GHz (W Band)

DLW10-U387-0R5 is a WR-10 RF waveguide termination for W-Band operation from 75 to 110 GHz, with 0.5 W average input power at 25°C. It is designed to absorb RF power on unused ports or line ends in millimeter-wave assemblies, helping reduce reflections and maintain controlled RF behavior.

This waveguide termination uses a UG-387/U flange and is manufactured in copper with a gold-plated finish, making it suitable for precision mmWave applications where mechanical accuracy and reliable electrical contact matter.

Role in the RF chain

A WR-10 termination is typically used to terminate unused ports, test ports, and secondary branches in millimeter-wave modules, subsystems, and lab setups. At W-Band frequencies, good matching is critical to limit return reflections and preserve measurement integrity or signal path performance.

Why choose this WR-10 termination

• Compatible with WR-10 systems across 75-110 GHz
• Standard UG-387/U mechanical interface
• 1.06 max VSWR for excellent match quality
• Copper body with gold plating for mmWave applications
• Designed for operation from -40°C to +70°C

DLW10-U387-0R5 is a strong fit for technical B2B catalogs when a compact WR-10 waveguide termination is needed for W-Band RF absorption.
