Description
The Effelsberg Direct Digitisation (EDD) system is a flexible platform for broadband radio astronomy, supporting observation modes ranging from single-dish spectroscopy to Very Long Baseline Interferometry (VLBI). Building on the existing EDD capabilities, we are developing a new Triband receiver system to simultaneously cover the K, Q, and W bands, providing an instantaneous digitized bandwidth of up to 12 GHz and an overall RF coverage of approximately 50 GHz. This design will enable coordinated observations across widely separated frequency bands, with particular emphasis on implementing multi-band phase transfer techniques directly within the EDD backend. Such integration aims to improve high-frequency VLBI coherence and sensitivity by transferring phase stability from lower to higher frequency bands in real time. We will present the receiver and backend architecture, the planned digitization and data transport chain, and the anticipated performance for VLBI and other high-frequency observing modes. This development represents a key step toward fully exploiting Effelsberg’s high-frequency capabilities for global VLBI and broadband science.
