Generic Model and Case Studies of Microwave Power Sensor Calibration Using Direct Comparison Transfer

This paper proposes a generic model for analyzing the microwave power sensor calibration by direct comparison transfer. The model is derived using a signal flow graph together with nontouching loop rule analyses. The proposed model is investigated through several case studies which are commonly encountered and provides a theoretical basis for practical applications. Finally, realizations of the derived calibration equations for some practical cases are also discussed.
