Semiconductor Solutions

Intelligent Electronics for the Connected World

At pSemi, we design and manufacture innovative semiconductor solutions.  We take what “can’t be done” and transform it into an industry first. Whether it is a cutting-edge design technique, a transformative architecture or a novel technology platform, our team explores new ways to make electronics smaller, thinner, faster and more efficient.

Our RF, power management and sensor products are designed into devices that are used by millions of people worldwide. You’ll find our integrated circuits in your smartphone, your cable modem, your laptop and your neighborhood’s new 5G base station.

Headquartered in San Diego, we have offices on three continents and a worldwide sales team to support our customers. Our offices are located in major global tech hubs to support our growing team of talented electrical engineers. 

We build intelligent electronics for the connected world.

RF SOI Pioneer

30+ Years of Semiconductor Innovation

Three decades ago, our founders set out to achieve what the industry thought was impossible: commercialize radio frequency (RF) silicon-on-insulator (SOI) technology. After overcoming the performance barriers and solving the technical challenges, SOI has moved into the mainstream, and the vision of a silicon RF front end has been transformed into reality.

Our disruptive innovations around SOI technology, RF switches and antenna tuners paved the way for new products in adjacent markets. Every day our engineers continue to challenge the “impossible.” We push the limits of integration and performance so that our products can exceed the market specifications of today and tomorrow.
