WF-0055 WR90 FXR Finned Waveguide Dummy Load. Mega’s Model Number WF-0055 is a Finned Dummy Load rated for 8.20 to 12.4 GHz, X-Band operation.
The FXR Dummy Loads product line, designs and IP were acquired by MEGA Industries from Microlab in 2014. MEGA supports and produces the full line of FXR Waveguide Loads designed for rugged high power use and to satisfy minimum cost and weight objectives.
The WF Finned loads employ heavy duty 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. For additional cooling fins see the WG series. These loads can be supplied to operate over the full indicated waveguide frequency band.
