Modelithics Inc. and IPDiA, have teamed up to develop Modelithics models for IPDiA’s high performance ultra broadband surface-mount silicon capacitor. Modelithics and IPDiA worked closely as part of the Modelithics Vendor Partner (MVP) Program to characterize the 10 nF low profile (100 µm) capacitor (UBSC 935 152 492 510).

Modelithics has developed two equivalent circuit model versions, one that features validation to 67 GHz, based on testing done in microstrip format offering substrate and pad scalability, and another that is validated to 110 GHz, using test data obtained with a coplanar waveguide fixture on quartz thin film. This 10 nF silicon capacitor in a 100 µm 0201 form factor shows the following performances:

  • Flat frequency response (insertion loss < 0.4 dB up to 67 GHz & < 1.2 dB up to 110 GHz);
  • Excellent return loss better than -20 dB;
  • Resonance free thanks to the capacitor single layer design of 50 μm thickness;
  • Zero piezoelectric effect and low dielectric absorption (0.05%) at least 12 times lower than ceramic capacitors;
  • Ultra low electrical variation over voltage and temperature (lower than 1%).

IPDiA is sponsoring FREE 90-day licenses for use of all Modelithics models available for IPDiA capacitors, which are also now included in Modelithics COMPLETE Library. This includes the two new equivalent circuit model versions for the 0201M (10 nF, 100 µm thickness, 11 V breakdown voltage), plus Modelithics S-Parameter data models for other values and variations of the ultra broadband silicon capacitor series. The IPDIA model sub-library is now available for easy installation and use in five popular microwave simulation tools: Keysight ADS, Keysight Genesys, NI AWR Design Environment, ANSYS HFSS and Sonnet Suites.  For more information about the Modelithics-IPDiA simulation models, and to request a free trial, visit the IPDiA MVP page at https://www.modelithics.com/mvp/ipdia Use the promo code: IPDMVP for an extended free use period.
