Calibration and Verification Procedures at ARL for the Focus Microwaves Load Pull System

摘要

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.
