5G Acoustic Filters

Dr. Songbin Gong from the University of Illinois has developed a suite of technologies for the design strategy and method of fabricating acoustic front-end filters at various frequencies, including frequencies > 6 GHz. These acoustic front-end filters demonstrate high electromechanical coupling, high fractional bandwidths, as well as high quality factors. This is achieved through a combination of materials selection, resonator design, and filter design.

This technology:


  • Increases the frequency range and the fractional bandwidth of acoustic filters
  • Enables the future generations of wireless communication
  • Allows access to frequency bands above 6 GHz and provides the high FBW required for 5G communications
