Abstract
High power HBT process developed by UMS for X-band application have been space evaluated under CNES and ESA funding.The reliability assessment plan features high temperatures storage tests,DC life-tests,RF step test stress,ESD and radiation tests.A set of evaluation test vehicles was defined for this purpose.Activation energy have been determined,failure rate calculations are in line with the space requirements
