Abstract:

The contract for Battlefield Online with Superconductive Systems build upon the success of previous AFRL contracts to develop components based on superconductive electronics for spread spectrum modems. The prior work had demonstrated a low power chip that operated at 2 GHz and performed spread spectrum functions. This contract developed a Digital Correlator and a rapid Synchronizer and demonstrated that the correlation and synchronization could be performed with superconductive digital electronics. The Digital Correlator demonstrated correct mixing of 2-bit Data with Code and accumulation of the correlation sum at speeds up to 320 MHz. It correctly accumulated single inputs at rates up to 3 GHz. The synchronizer demonstrated most of its functions at low speed. Another task supported the design of a Glue Chip for use in a Crossbar data switch. The Glue Chip is part of a multichip module that forms the switch fabric. The Glue Chip was designed to have high sensitivity to weal signals, but changes in the design of the Switch Chip created a stronger signal, so the sensitive Glue Chips were not built. The high-speed circuits developed under these AFRL contracts have the ability to transform communications. The report contains two scientific papers Spread Spectrum Data Transfer from Dewar to Dewar at 2 Gigachips per Second, and Digital Correlator for a Spread Spectrum Modem Operating at 2 Gigachips per Second.
