RF Waveguide Termination, WR-12, UG-387/U, 0.5 W, 60.5-91.9 GHz (E Band)

DLW12-U387-0R5 is a WR-12 RF waveguide termination designed for millimeter-wave operation from 60.5 to 91.9 GHz, with 0.5 W average input power at 25°C. It is intended to absorb RF power on unused ports, line ends, and secondary branches in mmWave assemblies, helping reduce reflections and maintain controlled RF behavior.

This termination features a UG-387/U flange and is manufactured in copper with a gold-plated finish, making it suitable for high-frequency systems where mechanical accuracy and reliable electrical contact are important.

Role in the RF chain

A WR-12 waveguide termination is typically used to terminate unused ports, test ports, and auxiliary branches in millimeter-wave modules, subsystems, and laboratory setups. Good matching helps minimize return reflections and supports more stable RF performance across the signal path.

Why choose this WR-12 termination

• Compatible with WR-12 millimeter-wave systems
• Standard UG-387/U mechanical interface
• 1.05 max VSWR for excellent match quality
• Copper body with gold plating for mmWave use
• Operating range from -40°C to +70°C

DLW12-U387-0R5 is a solid choice for technical B2B catalogs when a compact WR-12 waveguide termination is needed for RF absorption from 60.5 to 91.9 GHz.
