Research Institution
In true Digital-RF receiver technology, the RF signal is sampled directly at the antenna and processed digitally at high speeds. This requires an ultrafast ultra-linear analog-to-digital Converter (ADC) followed by ultrafast digital signal processing (DSP). High-speed clocks, in the 20 - 120 GHz range, are required for both the ADC and the DSP. For best performance, the ADC clock must have extremely low short-term jitter, preferably 10 fs (0.01 ps) or less. HYPRES has previously demonstrated that a Long Josephson Junction (LJJ) oscillator may be used as a clock source that meets all of these requirements, and can be integrated with rapid-single-flux-quantum (RSFQ) superconductor digital circuits. HYPRES proposes to develop a parametric family of high-frequency LJJ clocks, and to fabricate and test such an on-chip clock, phase-locked to an external low-frequency reference oscillator for long-term stability. In Phase II, a programmable modular multi-rate clock will be integrated with a superconducting ADC and DSP to provide a complete, compact digital-RF receiver system for Army communications.
