Need a SiP built for your requirements?
If our standard Nar Series modules aren't a perfect fit for your project, we design a custom System-in-Package (SiP) that combines the processor, memory, power, and connectivity blocks into a single package tailored to your needs. We take on the RF calibration, power-tree validation, and test burden; you go to production with a single part number.
