| Abstract: | The range of current attenuation calibrating system is too small to meet the requirement of calibration of step attenuator with high attenuation value.Based on the analysis of the T-matrix method,a new measurement scheme is proposed to measure nonprogrammable step attenuator with high value.The principle and implementation process of T-matrix method are detailed.It is proved to be feasible by the actual test.It can be a set of practical solutions to the calibration of attenuation with high value. |
