Resonant is a late-stage development company creating innovative filter designs for radio frequency front-ends (RFFEs) for the mobile device industry. The 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. Filters are a critical component of the RF front-end that select the desired radio frequency signals and rejects unwanted signals.
Using a patented, fundamentally new technology called Infinite Synthesized Networks(tm) (ISN), Resonant has developed a new method of designing RF filters that can displace conventional filters by providing significant cost and size reductions, fewer components and improved performance. ISN can improve Surface Acoustic Wave (SAW) filters to work in difficult, Bulk Acoustic Wave (BAW) bands with performance that is competitive with best in class products that exist on the market today. These capabilities will also allow Resonant to create filter designs that tune to multiple bands. These tunable designs would replace several existing filters while significantly reducing the overall size and cost of the RFFE.
