Engineered for precision microwave, millimeter-wave (mmWave), and sub-millimeter wave systems, our comprehensive portfolio of Waveguide Loads and Terminations (Dummy Loads) delivers exceptional power absorption, ultra-low reflection coefficients, and superior thermal stability. Covering a vast frequency spectrum from 8.2 GHz up to 220 GHz, our product lineup spans rectangular waveguide sizes from standard WR-90 down to ultra-high-frequency WR-8, WR-6, and WR-5 bands.
Whether you are testing high-power radar transmitters, designing satellite communication earth stations, calibrating network analyzers, or developing advanced 6G and terahertz research systems, our waveguide loads provide reliable power dissipation. Manufactured using high-grade precision-machined aluminum, oxygen-free copper (OFC), or brass with specialized lossy absorbing elements, each load is optimized for minimal VSWR and robust thermal performance across broadband frequencies.
What is the primary function of a waveguide load (dummy load)? A waveguide load (or termination) is designed to absorb all microwave or millimeter-wave power incident upon it with minimal reflection. It is commonly used to terminate unused ports of directional couplers, power combiners, or transmitters during testing to prevent damaging reflections.
Do you offer high-power water-cooled or conduction-cooled waveguide loads? Yes! While standard low-to-medium power loads utilize natural convection finned heatsinks, we also offer custom high-power configurations featuring extended cooling fins or liquid/water-cooling channels for demanding high-power applications.
Can you supply sub-mmWave loads for WR-8, WR-6, and WR-5 bands? Absolutely. We specialize in precision micro-machining for high-frequency sub-mmWave and terahertz bands up to 220 GHz, ensuring strict dimensional tolerances and low VSWR performance across WR-8, WR-6, and WR-5 specifications.
