dc.description.abstractThis paper explores the potential of a two-material piezo drop-on-demand process for the realization of monolithic four-way power dividers. Integration concepts using grounded coplanar waveguide transmission lines with different geometrical profiles, i.e. solid- and dielectric-filled conductors, are examined to observe their suitability for the power divider realization. For proof-of-concept validation purposes a prototype of the four-way power divider was manufactured and tested at Ku-band. It demonstrated a reflection coefficient |S11| ≤-10 dB from 11 GHz to 14.9 GHz that corresponds to a fractional bandwidth of 30.46%. The proposed solution has an average insertion loss of 5.2 dB that includes the loss of the coaxial connectors.en
