Non-conventional beyond-the-state-of-the-art signal processing schemes require parallelism, scalability, robustness and energy efficiency to meet the demands of complex data-driven applications. Magnonic and spintronic circuits are potential candidates that can aid in fulfilling these requirements. Hereby, an experimental proof-of-concept for a novel hybrid magnonic-spintronic device is proposed. Using spintronic auto-oscillations, this device can generate a broad, GHz-wide RF signal and filter this signal in a selective and tunable manner using a magnonic circuit. This research is funded by the European Research Council within the Starting Grant No. 101042439 "CoSpiN" and by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) - TRR 173-268565370 (project B01).
