We describe the electromagnetic and thermal design, performance, and fabrication for two types of radiometric- waveguide load calibrators. A simple theory is presented and used to minimize the total volume of the absorber structure. These devices have been used from room temperature to below 4 K in microwave to millimeter wavebands. The estimated precision of the calibrator is better than 1 mK absolute at temperatures near 2.7 K.
