Peregrine Semiconductor is a supplier of the industry's most advanced RF and mixed-signal communications ICs which are ideally suited for the wireless infrastructure and mobile wireless; broadband CATV/DTV; communications infrastructure; and high-reliability markets.

Manufactured on the Company proprietary UltraCMOS mixed-signal process technology, Peregrine products are uniquely poised to meet the needs of a global RF design community in high-growth applications such as WCDMA, EDGE and GSM digital cellular and mobile TV; broadband communications such as DTV/PCTV/DVR and telecom infrastructure; and in high-reliability applications such as industrial, automotive, military and satellite systems. Peregrine products feature monolithic integration and ease-of-development, which are essential to timely and cost-effective application design bycustomers. Peregrine UltraCMOS devices are manufactured through strategic relationships with world-class CMOS foundries located in Australia, Asia and Japan. The Company, headquartered in San Diego, California, maintains global sales support operations and a worldwide technical distribution network.

Peregrine ’s semiconductor solutions use proprietary UltraCMOS? technology, which enables the design and manufacture of a single chip integrated with multiple RF mixed-signal and digital functions. UltraCMOS RF process technology is an advanced form of silicon-on-insulator (SOI) technology that combines the basic advantages of the most widely used semiconductor process, "standard CMOS," with a highly insulating substrate. A unique generation of products using UltraCMOS technology is called "STePs", each node enables greater design flexibility and enhanced RF performance. Peregrine Semiconductor has also engineered design enhancements, including patented HaRP ? technology.

Since its inception, Peregrine Semiconductor has focused its engineering resources on designing RF ICs which deliver best-in-class performance from antenna in to data out. The Peregrine UltraCMOS product portfolio achieves new milestones in monolithic integration, linearity, ultra-low power consumption and value, and showcases CMOS achievements including cellular handset switches and 13 GHz rad-hard prescalers.

Peregrine Semiconductor is now renamed pSemi (TM), pSemi builds upon Peregrine Semiconductor’s 30-year legacy of technology advancements and top-ranked intellectual property (IP) portfolio but adds a new mission—to enhance Murata’s world-class capabilities with high-performance semiconductors.

Peregrine is product portfolio consists of UltraCMOS, GSM Chips.
