HYPRES received $800K to develop a compact cryocooler and its superconducting 2 MHz-2 GHz direct-conversion all digital receiver. The cryocooler and receiver are key components in the company’s work to deliver to the DoD the industry’s first all-digital transceiver (ADT) for wireless communications. The funds came from the Department of Defense’s Small Business Innovation Research (SBIR) program.
The ADT will be capable of digitizing multiple radio signals at RF directly from the antenna without any analog pre-processing, and digitally combine and pre-distort outgoing signals at RF frequencies. This “wideband direct-digitization,” as it is known, will provide orders-of-magnitude performance gains and cost reductions in all but the small mobile software radio applications, including Satellite Communications (SATCOM), Signals Intelligence (SIGINT), Electronic Warfare (EW), and Joint Tactical Radio System (JTRS) programs.
