Abstract
Modern radio frequency (RF) communication systems require more efficient and flexible use of wider bandwidths at higher carrier frequencies, which can be achieved only by direct digital representation of the RF signal itself. New advances in ultrafast superconductor circuits enable digital-RF technology extending all the way to microwave SATCOM bands (X, Ka, and EHF). Previously, HYPRES built and delivered to US Army CERDEC a superconducting digital-RF X-Band receiver, clocked above 30 GHz, and demonstrated reception of signals from XTAR, DSCS, and WGS satellites. The present project focuses on the development of two critical components of a digital-RF SATCOM: (1) a digital-RF signal combiner, and (2) an RF digital-to-analog converter (RF-DAC). Phase I will focus on the development of practical system architectures that optimize the tradeoffs between circuit complexity and speed, bits and bandwidth, superconductor and semiconductor, cryogenic and uncooled, and digital and analog. The chosen designs will be laid out in the Phase I Option, and fabricated and tested during Phase II. They will then be packaged with other circuit components and integrated with a compact cryocooler to form a complete digital-RF transceiver for SATCOM and other applications.
