Abstract : The program encompasses the development of an ultra reliable, lightweight, manpack receiver/transmitter. The report describes continuing design effort on the receiver/transmitter circuitry, detailed mechanical design of the receiver/transmitter case and modules, and thick film hybrid circuit layout and fabrication. The transfer of the initial circuits into hybrid form was started this quarter. Many of the circuits followed the pre-contract development work very closely and are currently undergoing the hybrid conversion process. More complex circuits, which involved detailed tradeoffs and investigation, are still being evaluated in breadboard form. The design support studies were continued in the areas of Reliability and Value Engineering. A complete first prediction of reliability (MTBF) was made, and a number of value engineering tradeoffs were carried to the point of preliminary conclusions, resulting in the selection of optimum design approaches.
