| With the development and application of communication technology, the microwave devices are applied more and more widely, especially in military equipment field. For most of the military equipment, they are in storage, testing and other non-working status most of the time; in order to ensure its proper combat readiness, equipment storage reliability evaluation is particularly important. Intermediate frequency logarithmic amplification system is an important component in radar receiver module. Through researching the relevant literature of intermediate frequency logarithmic amplifier, main failure physics model of microwave components was obtained and failure criterion was determined. The component activation energy was calculated from high temperature accelerated life test data. Components’room temperature storage life was predicted. |
