Alternative Power Standard Realization at Radio Frequency

Modern ac-dc transfer equipments can operate up to 1 GHz at least. These equipments and the related ac-voltage measurements may be attractive for calibrating high frequency power sensors in term of ac-dc transfer difference instead of effective efficiency. Furthermore, below 30 MHz, the ac-voltage standard can be also used as powerful alternative and complement to the microcalorimeter technique for the realization of the RF power standard. In the paper experimental measurements and data analysis are presented that prove the previous assertions.
