STQ-2016Z Reliability Qualification Report
XIII. FIT Calculation from Accelerated Life Test Data
The following data demonstrates the results from accelerated life tests performed on the
Sirenza 4A SiGe HBT Process. The test was performed on 791 units running at a peak
o
junction temperature up to 195
C. The FIT rate calculation can be found below. The FIT
rates were generated assuming 1 failure. In reality, there were no failures, making this a
very conservative calculation.
