Report No. ARL-TR-3985
Authors: Benjamin D. Huebschman
Date/Pages: November 2006; 30 pages
Abstract: When evaluating the performance of technologically innovative microwave devices, it is important to be able to validate the performance of the system performing the measurements. The theory behind the measurements used in recent Army Research Laboratory testing of the Gallium Nitride high electron mobility transistor devices is described. The verification of calibration used in the measurement is outlined in detail including a metric by which the accuracy of the validation can be judged.
