Description
The trend to all digital processing and software defined radio receivers was driven by a lack of flexibility, reliability and loss in the analog processing block of receivers. While the flexibility of software defined radio is clear, cryogenic temperatures offer an opportunity to exploit lower thermal noise in standard components and increase overall system efficiency and performance by utilizing the superconductivity. To date, individual cryogenically cooled components have been studied, in some cases very well, but the opportunity to exploit cryogenic cooling throughout the receiver chain is neither well documented or exercised broadly. Further, as computing looks toward a new era, specialized computing is becoming more acceptable. This provides a further opportunity for analog processing, and some processor do already exist. Finally, the full exploitation of cryogenic cooling suggests utilizing both analog and digital techniques to process within the system construct of a typical low temperature cryocooler. This talk will suggest opportunities as well as benefits for improving system performance through analog signal processing.
