Analysis of the functioning and long-term degradation of high-frequency transistor oscillator performance
Abstract
Analysis of the functioning of an electronic circuit is an essential step prior to evaluation of degradation of performance with time (ageing of components, variation in the characteristics, etc.). The functioning of a high-frequency transitor oscillator is being analyzed using the computer-aided-design (CAD) program 'ESAMEC', with emphasis on its modelling, research on the nominal operating point, and the need to obtain data on the variation of critical parameters with time. The latter data is essential in order to realistically predict the long-term degradation of the circuit analyzed, particularly when it is designed to be flown on board an applications satellite that has a planned lifetime of the order of five to seven years.
