Abstract

This paper describes a new procedure aimed to improve the effectiveness of real-time load-pull calibration. Load-pull measurement accuracy is strongly affected by calibration residual uncertainty. The novel methodology reduces this uncertainty contribution by means of error terms optimization. The proposed method has been tested with simulations and applied to actual measurement data. Considerable improvements have been achieved
