Direct digitization using superconducting data converters
Direct digitization is the ultimate enabler for future wireless communications. It refers to the ability to bring the digital domain as close to the antenna as possible, on both the receive and transmit ends of the radio transceiver system. It's a goal that remains just out of reach for systems based on traditional semiconductor technology and conventional data converters. Through the use of superconducting microelectronics technology and new, high-performing analogto-digital and digital-to-analog converters, however, direct digitization is firmly in reach....
Using behavioral models to drive RF design and verify system performance
A new generation of software tools for model-based design is enabling the creation of system-level models that system architects can use to evaluate the RF design specification. These flexible design environments allow information to flow top down and bottom up. Before, during and after the circuitry for the components and modules is being designed, the same system-level model can incorporate ever more refined performance information in order to determine the impact on systemlevel performance....
