What pSemi does
pSemi Corporation is a fabless semiconductor company headquartered in San Diego, California, that designs and manufactures RF and power-management integrated circuits. The company operates as a wholly-owned subsidiary of Japan's Murata Manufacturing Co., Ltd., following its 2014 acquisition and branding shift from its prior name, Peregrine Semiconductor. Founded in 1990, pSemi pioneered radio-frequency silicon-on-insulator (RF SOI) technology and now maintains 100+ U.S. patents across 16 generations of its proprietary UltraCMOS and UltraCMOS+ platforms. In 2017 it acquired Arctic Sand Technologies, adding 250+ patents in capacitor-based power conversion and establishing its power-management IC franchise.
The company's product portfolio spans RF switches (including SPDT, SP4T, and multi-throw devices covering kHz to 67 GHz), digital step attenuators, RF phase and amplitude control products, RF mixers and limiters, mmWave components, Wi-Fi front-end modules, and a growing power-management line built around charge pump switched-capacitor converters, 2-stage regulators, and multi-level buck converters. Notable recent products include the PE42424 SPDT switch for Wi-Fi 6E/UWB, the UltraCMOS+ PE42544 and PE42429 high-isolation switches, the PE26100 multi-level buck converter for fast-charging, and the PE25304 charge pump power module for humanoid robotics. End markets served include mobile devices, automotive, consumer electronics, communication infrastructure, cable broadband, IoT, and test and measurement.
Commercially, pSemi sells quote-based B2B through a global network of channel partners, including RFMW (which operates an online storefront), Richardson RFPD, Digi-Key Electronics, and WPG Holdings, supplemented by regional direct sales teams covering the Americas, EMEA, Japan, Korea, China, Taiwan and SEA, and India. Pricing is not publicly disclosed and contracts are typically multi-year. The company qualifies for demanding end markets via ISO 9001:2015, AS9100D, ANSI/ESD S20.20, TISAX AL2, ISO/TS-16949, and AEC-Q100 certifications, and is an active member of standards bodies including 3GPP, AEC, MIPI Alliance, OpenRF, and IWPC. pSemi participates in major industry events such as APEC and the International Microwave Symposium to launch new products.
