pSemi Corporation | Advanced RF SOI & UltraCMOS Technologies

pSemi (formerly Peregrine Semiconductor) is a leading fabless semiconductor company specializing in RF, analog, mixed-signal, and power management integrated circuits. Headquartered in San Diego, California, USA, pSemi has over 30 years of semiconductor innovation and has been a wholly owned Murata company since 2014.

The company pioneered commercial RF Silicon-on-Insulator (RF SOI) technology, enabling highly integrated, low-loss, and high linearity RF solutions used in smartphones, wireless infrastructure, IoT devices, automotive electronics, cable broadband, and aerospace applications.

Today, pSemi develops innovative semiconductor products for 5G infrastructure, Wi-Fi, cellular handsets, satellite communications, automotive connectivity, cable broadband, industrial automation, and power conversion.

Their invention of UltraCMOS® technology revolutionized the RF industry by allowing the performance of compound semiconductors to be combined with the integration and cost benefits of standard CMOS.

Key Product Highlights & Selection Guide

Key products are RF switches, digital step attenuators (DSAs), phase tuners, Monolithic Phase & Amplitude Controllers (MPACs), RF Mixers/Limiters, Front End Modules (FEMs), LNA modules, digital tunable capacitors, power management ICs and mmWave transceivers.
When navigating pSemi’s catalog, focus on insertion loss and isolation metrics. Their DSAs and switches are ideal for automated test equipment and phased array radars. Choose the exact bit resolution for DSAs based on how fine your amplitude control needs to be.
The other selection parameters switch configuration (SPDT, SP4T, SP8T etc.), noise figure, linearity (IIP3, OIP3), output power, Phase and amplitude control resolution etc.
