The application of integrated circuits in analog communications equipment was demonstrated by the development of the IF-video functional assembly of the Mark X IFF Transponder. The IF-video assembly utilizes a linear-logarithmic amplifier technique. Successive detection from each amplifying stage with progressive signal limiting yields output voltage increments proportional to the input voltage ratios. This technique is more readily implemented with state-of-the-art integrated circuits. Various integrated devices were evaluated in typical circuit configurations to select one device to perform all circuit functions IF amplification and video detection and amplification for the assembly. The primary design and development criteria considered in this project were cost, performance, reliability and weight. Evaluation of the final assembly demonstrated positive improvements in these criteria over the conventional design. Author
