A Low Power RC-Coupled VHF Amplifier Designed for Fabrication by Hybrid Microcircuit Techniques.

摘要

A low power,high gain,VHF amplifier was designed for use in the RF amplifier chain of a tuned radio frequency receiver for satellite applications. The curcuit design was directed toward a topology and component use compatible with efficient fabrication as a hybrid microcircuit. Operating parameters were selected to optimize the relationship of using the least number of components while achieving the highest gain efficiency (ratio of RF gain to DC power consumption). The report describes both the circuit design and the packaging techniques. Detailed electrical characterization of the resulting five-stage amplifier is also presented. (Author)
