Microlab WF-0055
Finned Dummy Loads
Waveguide Loads, WF series Finned Dummy Loads 1.12 - 40 GHz Extremely Rugged High Power Loads High Temperature Refractory Load Elements Transverse Cooling Fins Available with most Common Flanges Microlab WF series dummy loads are the commercial equivalent of the standard military DA loads. Models are designed to meet the requirements of MIL-D3954A in all electrical and mechanical respects for bands from 1.12 to 40.0 GHz. The WF loads employ transverse cooling fins and high temperature refractory load elements designed to meet the requirements of MIL-D-3954A. These 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. The WG series is a similar finned design, but with enhanced heat transfer. For lower powers unfinned models may meet the need, see the WE series. These loads can be supplied to operate over the full indicated waveguide frequency band. Generally faster delivery and a more economical unit can be furnished for use over narrower frequency ranges.
