DLW19-U383-0R5 is a WR-19 RF waveguide termination designed for millimeter-wave operation from 39.2 to 59.6 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-383/U-Mod 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.
