Peregrine Semiconductor Corporation- Fixed Digital Step Attenuators

Peregrine Semiconductor Corporation, founded in 1990 and headquartered in San Diego, California, is a leading fabless supplier of high-performance radio frequency (RF) integrated circuits. The company pioneered UltraCMOS technology, a proprietary silicon-on-insulator (SOI) process that delivers superior RF performance, including exceptional linearity, low insertion loss, and high isolation. Its core product portfolio includes RF switches, digital step attenuators, phase shifters, power limiters, mixers, and integrated RF front-end modules. These products serve frequency ranges from DC to 6 GHz and beyond, addressing markets such as wireless infrastructure, mobile devices, aerospace and defense, test and measurement, automotive, and industrial. Peregrine is recognized for enabling advanced 4G and 5G communications in smartphones, base stations, and IoT devices. In 2014, the company was acquired by Murata Manufacturing Co., Ltd., becoming a wholly owned subsidiary while maintaining its brand identity and R&D capabilities. With over 400 issued patents worldwide, Peregrine remains a technology leader in RF SOI solutions, holding a dominant market share in high-performance RF switches. Its customer base includes major OEMs and network equipment providers globally. The company continues to drive innovation within Murata’s semiconductor group, focusing on low-power, high-frequency designs for next-generation connectivity.
