Mobile filter start-up Resonant Inc. has signed an agreement with an established surface acoustic wave (SAW) and GaAs foundry serving the RF market, the third foundry agreement Resonant has secured to support its design services business model. The agreement expands the manufacturing capacity available for Resonant's filter designs and gives licensees additional foundry choices.

In a press release, Resonant said the new addition is a “full service” foundry serving first-tier filter suppliers and processing the filter designs for two Resonant licensees.

Resonant's Infinite Synthesized Network® (ISN®) foundry program includes non-captive SAW foundries and backend and packaging partners, the latter enabling Resonant's filters to be integrated into front-end modules.

George Holmes, CEO of Resonant, said,

“Mobile filters are the strategic component in the RF front-end. Any module supplier must have a stable supply of this critical device to be successful, and Resonant is providing the fabless/foundry ecosystem necessary to support this market expansion.


In addition, our ISN platform capabilities have been expanded such that we can now optimize the integration of our filter designs into the module, providing optimal performance of the entire module for our customers.”
