Abstract :
THE application of transistors to military electronicequipment designs has revolutionized the concepts of size, weight, power requirements, and structure. The performance of certain functions using transistors instead of tubes results in a tremendous saving in power, thereby reducing the cooling-air requirements, and allowing in many instances an order-of-magnitude reduction in size and weight. Transistors, in contrast to tubes, can stand vibration and shock as well as the other component parts used in electronic equipments. This has reduced the need for specific structures and shock mounting. The use of etched-wiring techniques for component-part mounting and interconnection, combined with potted modular structures is feasible when using transistors. The transistor has revolutionized the design concepts of military electronic equipment, by allowing a reduction in power requirements, weight, and space.
