Waveguide Matched Load
Model: WL-SERIES
Waveguide matched loads are essential components in waveguide measurement systems, designed to absorb microwave power, eliminate reflections, and provide a near-ideal matched termination. This series covers 8.20–75.8 GHz, with standard rectangular waveguides from BJ100 to BJ620. Typical VSWR across the full waveguide bandwidth is as low as 1.02. Available in aluminum or steel, with surface treatments including silver plating, gold plating, nickel plating, passivation, and conductive oxidation. Length, flange, material, surface treatment and electrical specifications can all be customized.
