How to Calibrate RF Power Sensor Linearity

Calibrating RF power sensors for linearity is becoming commonplace in routine power sensor calibrations. While many thermal power sensors have virtually undetectable linearity errors, the inherent non-linear behaviour of diodes make linearity testing of single and multi-diode sensors an essential requirement for a calibration to be considered sufficient and complete. This webinar overviews popular sensor technologies, outlining the linearity compensation techniques employed, and describes how an RF Reference source designed specifically for calibration can be used to perform the required measurements easily and quickly, manually or automated.
