Abstract

We present a method to obtain a broadband on wafer calibration from 45 MHz to 40 GHz for variable temperature, which requires three standards: a thru-reflect, and series-resistor. The maximum error of this technique compared to a benchmark 9 standard multiline thru-reflect-line is comparable to the repeatability of the benchmark calibration. The series-resistor standard is modeled as a lumped-element π -network. We show that the model is stable over a long times, and compare the calibration to multiline thru-reflect line as a function of time. The approach is then demonstrated at variable temperature, where the model parameters are extracted at 300 K down to 20 K to determine their temperature dependence. The resultant technique reduced the total footprint of the calibration standards by a factor of 17 and measurement time by a factor of 3.
