INTEGRATED PRECISION TUNING SYSTEM

A brief history of the Precision Integrated Tuner program from its inception to date is given. Some of the more interesting highlights in the evolution of the final design are presented, including a brief outline of the factual data to be presented. A summary of design considerations which affect the relative importance of tuner performance characteristics is discussed. The summary is written with emphasis on speech communications equipment in the HF range, particularly single sideband manpack communications equipment. Because of the advanced development nature of the program, economic considerations which might considerably affect certain performance trade-offs are given littel emphasis. Data is presented on the following topics: distortion in forward biased junction diodes, distortion in reverse biased junction diodes-the VVC, junction transistor RF amplifiers, voltage tuned RF tuner design, and test data from the final development models.
