ANALYSIS OF THERMAL AND FREQUENCY CHARACTERISTICS OF THIN-FILM ATTENUATORS FOR HF AND SHF BANDS
The analysis of thermal and frequency characteristics of thin-film attenuators on the basis of distributed resistive structures has been made. Such attenuators providing an absolute measure of attenuation are widely used in HF and SHF measuring and control equipment. An algorithm has been proposed to calculate the power released in the resistive thin film and its steady-state temperature.
