Resonant is creating innovative software, intellectual property (IP) and a services platform that has the ability to increase designer efficiency, reduce the time to market and lower unit costs in the designs of filters for radio frequency (RF) front-ends for the mobile device industry. The RF front-end (RFFE), is the circuitry in a mobile device responsible for analog signal processing and is located between the device's antenna and its digital baseband.

The RF front-end industry is undergoing dramatic increases in growth and complexity due to:

  • Band proliferation
  • Carrier Aggregation (CA)
  • Multiple-Input, Multiple-Output (MIMO) antenna design

The filtering problems of RF front-ends are rapidly becoming so complex that very few companies can solve them. At Resonant, we are developing a fundamentally new technology that we call Infinite Synthesized Networks®, or ISN®, to configure and connect resonators, the building blocks of RF filters. Filters are a critical component of the RF front-end used to select desired radio frequency signals and reject unwanted signals. Our ISN® platform allows us to develop unique, custom designs that address the increasing complexity of the RFFE due to carrier aggregation (CA), by both reducing the size of the filter and improving performance. Our goal is to utilize our ISN® platform to support our customers in reducing their time to develop complex filter designs and accessing new classes of filter designs, and to do it more cost effectively.
