A Terminator is installed on Port 3, and BiasTee is placed in a 77K environment, and S-parameter data is extracted when the data is stable.
There is a slight difference in the data around 20 GHz depending on the measurement date, due to the state of Calibration, and the accuracy of the measurement data around 20 GHz varies.

"Before" placing in 77K environment for 30 minutes

"After" placing in 77K environment for 30 minutes

Data under 77K environment for the 20th time, in the case of 20 cycles of placing BiasTee under 77K environment and then thawing at room temperature

Data after 20th time of thawing, in the case of 20 cycles of placing BiasTee under 77K environment and then thawing at room temperature
