The Tactical Signal Intelligence SIGINT Technology TST program objective was to develop optically controlled positive-intrinsic negative PIN diode radio frequency RF switches and demonstrate their feasibility to enhance electromagnetic interference EMI immunity, sensitivity, speed, and reliability in front-end SIGINT systems. Project members surveyed, analyzed, and selected U.S. Army, Air Force, and Navy SIGINT systems for optoelectronic switch development goals developed switch circuit designs for these applications, developed switch technology to implement these designs and to assess its present performance and limitations, and demonstrated feasibility in the laboratory and in SIGINT system equipment where possible. The TST Program developed optically controlled PIN-diode-based RF switches for potential TST applications. Applications included EMI immunity, bias-free operation, switching speed, low noise, power handling, and reliability.
