Abstract :
The paper reports high temperature on-wafer microwave characterization setup for AlGaN/GaN HEMT devices. S-parameters were on-wafer measured in frequency range up to 40 GHz in wide bias point settings as well as microwave parameters fT and fmax were measured and visualized in the temperature range from room temperature up to 425°C. Significant influence of temperature on microwave properties was observed.
