Abstract
Measurements at 43 GHz of the four noise parameters of very low-noise HEMTs (high-electron-mobility transistors) fabricated at several laboratories are reported. The measurements are facilitated by tunable waveguide-to-microstrip transitions which present known variable generator and load impedances to the device under test and are operable over a wide range of temperatures.<>
