TELEDYNE e2v BOOSTS RADIO SOFTWARIZATION EFFORTS THROUGH ITS LATEST MICROWAVE DATA CONVERTER DEVELOPMENTS

摘要

The objective of the project outlined here is to dramatically expand sampling bandwidth and extend technical capabilities of a wideband product portfolio driven by the Interstellar project vision and equally as a response to market need. Projecting direct conversion techniques into the microwave Ka-band is certainly a significant and challenging goal. However, previous developments already prove successful and result in economic implementations of direct to K-band approach using standalone components. It is also important to highlight this can be achieved for systems expected to meet the highest reliability levels for space operation including total ionizing dose radiation ruggedness. As each engineering pain point is tackled, Teledyne e2v envisages a time in the near future when highly scalable, system in package (SiPs) data converter modules; those combining multi-input/output ADC/DACs paired with microwave samplers and associated clock management, are dense enough to migrate ever closer towards the antenna. At this point, ultra-wideband CRs will have become a reality and the challenge of highly agile radio infrastructure will, at least at the physical layer have been largely solved. SDRs will have become a critical part in flexible SDNs.
