The primary object is the design and fabrication of advanced developmental models of dry, unbalanced nonradiating broadband dummy loads capable of dissipating CW or pulsed RF energy of 100 watts and one kilowatt average levels. The loads so designed are to have reduced physical dimensions over loads which presently represent the state of the communications art. The secondary object is the preparation of design plans for loads having a capability for dissipating CW or pulsed RF energy of 10 and 50 kilowatt average levels. A tentative design for a 1 kw dry load was completed. Theoretical and experimental studies of the various portions of the load indicate that the basic concepts are feasible. R. F. and thermal analysis predict load sizes may be scaled without basic difficulty. Experimental work done on a thermal mock-up of a 1 kw size load show that the temperatures attained by the various portions of the load are in close agreement with the predicted values. Test on carbon film elements for the 100 watt size load indicate no serious difficulties with the small units.
