WR-15 Sliding Matched Termination
The WR-15 Sliding Matched Termination is an adjustable waveguide load with a precision sliding mechanism for fine-tuned impedance matching operating within the 50 GHz - 75 GHz frequency range, commonly associated with the V-Band.
The sliding absorptive element can be repositioned along the waveguide to minimize reflections at a specific operating frequency. This adjustability makes it an essential component in waveguide calibration kits, providing a near-ideal matched load reference for TRL calibration and network analyzer measurements.

Frequently Asked Questions
What is a sliding matched termination?+
A sliding matched termination is an adjustable waveguide load with a movable absorptive element. By sliding the absorber along the waveguide, engineers can fine-tune the impedance match at a specific frequency, achieving very low VSWR. This makes it essential for waveguide calibration kits and precision tuning applications.
How is a sliding termination used in calibration?+
During a calibration procedure, the sliding mechanism allows the operator to adjust the position of the absorptive load to minimize reflections at the measurement frequency. Combined with short circuits and offset shorts, the sliding matched termination establishes a near-ideal matched load reference plane for network analyzer measurements.
What materials are used in RF Essentials WR-15 terminations?+
RF Essentials WR-15 terminations are manufactured from oxygen-free high-conductivity (OFHC) copper for the waveguide body with precision-machined brass UG-385/U flanges. All surfaces receive gold plating for superior corrosion resistance and consistent electrical performance over the full V-Band operating range.
