A High-Frequency Amplifier Synthesis Program. LINVIL Computer FORTRAN IV Program Performs Necessary Computations Plus Graphic Output

摘要

A FORTRAN IV program called LINVIL has been developed at the Pacific Missile Range, Point Mugu, California, for the purpose of designing high-frequency amplifiers. The input data supplied by the engineer include the four complex parameters of the Y-, Z-, G-, H-, F-, Script F-, or S-type, center frequency, bandwidth, sensitivity, and the source and load resistances. The computer printout furnishes the maximum available gain, the maximum gain compatible with the sensitivity requirement, the network stability factor (Linvill's C factor), the complex value of load admittance, the complex value of source admittance, the parallel RLC element values required as a load to realize the bandwidth, and the element values (L and C) required to match, at the operating frequency, the complex load and source admittances to the desired load and source resistances. This report includes a brief review of the Linvill technique, examples of various designs with various input data, guides for the user, and a complete FORTRAN IV listing. (Author)
