High Power RF Calibration Method with Artificial Intelligence

Abstract

An accurate RF power detection is highly desirable for wide range of RF applications [1] . The major error in measurement of high-power RF signal detection occurs due to non-linearities and system dynamics [2] . The error also varies based on the operational frequency because of the frequency dependency and non-linear characteristics of active devices [3] . One of the methods to improve the measurement error is to minimize the error by applying conventional control system at each discrete frequency. This requires power calibration of the RF system for large number of discrete frequencies which is not practical within the entire operational frequency bandwidth.
