ARINC Research Corporation has completed Phase I of the Microelectronic Transceiver Development Program, performed under Contract N00123-68-C-2520 for the U.S. Navy Electronics Laboratory Center, San Diego, California. This effort was conducted under the technical direction of Code S-240, and consisted of the following tasks; (a) A complete evaluation of the equipment, materials, procedures, and general capability of the NELC Hybrid Microelectronics Laboratory; (b) Expansion of this capability to fulfill the requirements imposed by prototype fabrication of the microelectronic transceiver hardware; (c) A review of voice-coding techniques applicable toward providing secure communications, and the definition of an optimum approach for use with the transceiver; and (d) The detailed design of the voice scrambler portion of the microelectronic transceiver. At the request of Code S-240, development of the remaining portions of the transceiver was delayed until completion of the voice scrambler section, since this represented the area of greatest risk in terms of compatibility with state-of-the-art electronics. The remaining (Phase II) effort of this program consists of the following tasks; (a) Establishment of procedures and personnel training as required to fabricate prototype transceiver hardware in microelectronic form; (b) Final development and evaluation of the scrambler portion of the transceiver; and (c) Design and development of the remaining transceiver circuitry.
