Intern, RF​/EM Design

pSemi Corporation is a Murata company driving semiconductor integration. pSemi builds on Peregrine Semiconductor’s 30-year legacy of technology advancements and strong IP portfolio but with a new mission—to enhance Murata’s world-class capabilities with high-performance semiconductors. With a strong foundation in RF integration, pSemi’s product portfolio now spans power management, connected sensors, optical transceivers, antenna tuning and RF frontends. These intelligent and efficient semiconductors enable advanced modules for smartphones, base stations, personal computers, electric vehicles, data centers, IoT devices and healthcare.

From headquarters in San Diego and offices around the world, pSemi’s team explores new ways to make electronics for the connected world smaller, thinner, faster and better.

The EM design intern will support RFIC design teams in EM optimization and design of advanced RF Front End ICs and modules for pSemi’s product development efforts for mobile wireless RF front end semiconductor products for cellular handsets. Products are expected to include multiple RF sub-circuits including switches, low noise amplifiers, bias networks, power amplifiers, filters, couplers, passive RF components and the analog/digital circuitry to control them.

The candidate will support products throughout the entire product life cycle from product definition through product release to end-of-life.
