Abstract
This paper presents the design and measurement results of two different MMIC impedance tuners for noise parameter measurements at ambient and at cryogenic temperatures. The first design covers the frequency range from 10 to 20 GHz, while the second tuner performs from 15 to 30 GHz. The performance under cryogenic conditions was validated at 7 K with dedicated test structures.
