A MICROMINIATURE AMPLIFIER WITH THIN-FILM PASSIVE PARTS

Abstract

A microminiature 30-Mc IF amplifier stage was fabricated from vacuum-deposited thin-film passive components and two inserted parts. The vacuum-deposited parts, thin films of nickel chromium, aluminum, and silicon monoxide, were laid down for use as resistors, conductors and dielectrics, respectively. In the deposition processes, dimensionally accurate masks are essential and they were achieved by the use of a spark erosion technique. A specially designed mask-and-substrate holder accurately indexed the masks relative to the substrates. Three models of this amplifier were made but one could not be used due to a short in the circuit. The other two circuits showed gains of 16.5 and 14.7 db. When one circuit was retested after storage in a desiccator for one year at room temperature, the gain was 15.1 db.
