Waveguide Dummy Loads
Microlab dummy loads are rugged high power units designed to satisfy minimum cost and weight objectives. Models are designed for bands from 1.12 to 40.0 GHz. These dummy loads employ high temperature refractory load elements designed to meet the requirements of MIL-D-3954A. The load elements are in direct contact with the waveguide walls for optimum heat transfer. They can withstand extremely high temperature, temperature gradients and thermal shocks. Convection cooled units are available to satisfy a variety of lower power requirements while higher power and temperature specifications can be met with our liquid cooled units. Superior performance is achieved by slight changes in physical dimensions, more efficient fin cooling and increased waveguide pressure.
