This work reports on the integration of RF functionalities in microwave waveguide components through the selective laser melting process. A specific integrated component has been developed for the relevant application domain of satellite communications. The component operates in the Ku-K bands and integrates a H-plane bend, a 90-deg twist and ninth-order pass-band filter. The AlSi10Mg prototype manufactured through selective laser melting exhibits excellent RF performances (return loss > 20 dB, insertion loss < 0.23 dB, and rejection > 60 dB), while significantly minimizing mass, envelope and mechanical complexity.

Abstract
This work reports on the integration of RF functionalities in microwave waveguide components through the selective laser melting process. A specific integrated component has been developed for the relevant application domain of satellite communications. The component operates in the Ku-K bands and integrates a H-plane bend, a 90-deg twist and ninth-order pass-band filter. The AlSi10Mg prototype manufactured through selective laser melting exhibits excellent RF performances (return loss > 20 dB, insertion loss < 0.23 dB, and rejection > 60 dB), while significantly minimizing mass, envelope and mechanical complexity.File in questo prodotto:
