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
junction temperature up to 195oC. 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.
