Abstract
Section titled āAbstractāThis paper demonstrates the fabrication process and RF testing of a monolithic Wilkinson power divider (WPD) on single-crystalline diamond (SCD). The Grounded Coplanar Waveguide (GCPW) and microstrip (MS) transmission lines (TLs), the via-less GCPW-to-MS transitions, and the ground plane in the WPD configuration are printed on a 5Ć5 mm2 SCD wafer with the Aerosol Jet Printing (AJP) technique using silver ink. The resistor is fabricated via a combination of thin-film process and standard photolithography using nickel chromium (NiCr). Our results show good RF performance from 22 up to 40 GHz, indicating that SCD is a good platform for the integration of high-power and high-frequency electronics on a single substrate using additive manufacturing techniques.
