  • Abstract
    The Second Generation Digital Receiver (DRX) is the new digitisation platform for the Australian Square Kilometre Array Pathfinder (ASKAP). The DRX is the result of the ASKAP Design Enhancement (ADE) project which was undertaken to improve the manufacturability of the prototype ASKAP hardware. The DRX is a 16 port optically fed direct sampled digitiser operating between 700MHz and 1800MHz. It processes up to 768MHz of instantaneous bandwidth and allows the selection of an arbitrary 384MHz to be transmitted to the beamformer.
