Abstract:

A longstanding problem with wideband radio receivers for sensitive naval applications (such as Signals Intelligence or SIGINT) is the high level of RF interference from co-located RF transmitters. This Phase II project will develop a new generation of analog-to-digital converters (ADCs) that exhibit unusually large dynamic range and linearity, for incorporation at the front-end of a digital receiver that may detect weak signals without saturation due to "co-site interference." HYPRES has been developing a superconducting digital-RF receiver system for the Navy and other DoD users, based on an ultrafast ADC sampled at 20 GHz, which exhibits an impressive spur-free dynamic range (SFDR) greater than 100 dB for a bandwidth of 10 MHz. Even further dynamic range improvement is possible with the use of advanced multi-rate architectures. In Phase I, we designed and demonstrated the operation of a high dynamic range "quarter-rate quantizer," which can operate on data streams as fast as 100 GHz, while the output data is processed at 1/4th the rate. In Phase II we will implement complete ADCs based on this multi-rate approach, which will increase the dynamic range of the ADCs by at least 2 bits, in addition to a 1.5 bit increase associated with ongoing process improvements.
