Abstract :
This paper proposes a different modeling technique for analyzing the microwave power sensor calibration by direct comparison transfer. The model is established by using signal flow graph together with non-touching loop rule analyses. The realization of the banded calibration system from 50 GHz to 110 GHz by WR15 and WR10 connections is also described.
