Hypres’ new, superconductor-based receiver is simpler, cheaper, and more flexible. At its heart is an integrated circuit that includes a niobium RSFQ (rapid single flux quantum) analog-to-digital converter and digital signal processor. At around a few picoseconds, the RSFQ circuit’s characteristic response time is short enough to process multi-gigahertz signals. What’s more, the Hypres receiver needs only one low-cost analog wideband filter, not half a dozen or so higher-cost narrow-band ones; dispenses with local oscillators; and can handle a wideband signal without splitting it into channels. If the signal is reconfigured for different frequency band locations, the receiver can be preprogrammed. No new hardware is needed.
