Abstract :
An RF-stressed accelerated life test was performed to establish the reliability of the recently developed high power HEMT MMICs at 44 GHz. The results showed a MTF (median time to failure) of 1.7/spl times/10/sup 6/ hours at 125/spl deg/C channel temperature with the activation energy of 1.6 eV. The failure mode was a gradual output power degradation. A combination of surface states degradation and gate sinking were postulated as the failure mechanisms.<>
