Aalto University’s Metsähovi Radio Observatory is upgrading its 14 m radio telescope with a state-of-the-art triple-band receiver designed and built by the Max Planck Institut f€ur Radioastronomie. This receiver enables simultaneous dual-polarization observations across K (18 GHz to 26 GHz), Q (34 GHz to 50 GHz), W1 (80 GHz to 96 GHz), and W2 (100 GHz to 116 GHz) bands, significantly enhancing sensitivity and bandwidth for single-dish astronomical studies. To complement this upgrade, we developed a cutting-edge digital backend using Radio Frequency System-on-Chip boards to digitize and process the receiver’s signals. This article presents the initial development steps, including prototype implementation and simulation results.
