Peregrine半导体公司是Murata公司的一员，是射频SOI(绝缘体上硅)技术的奠基者，是提供高性能射频集成解决方案的领先的无晶圆厂供应商。自1988年以来，Peregrine和它的创始团队一直在完善UltraCMOS®技术──这是SOI方面拥有专利权的先进技术， 提供解决射频市场的最大挑战所需要的性能，例如线性度。由于Peregrine半导体提供的产品是单片集成方案，具有最好的性能，是汽车、宽带、工业、物联网、军工、移动设备、智能手机、空间技术、测试和测量设备和无线等市场的领先公司完全可信赖的选择。Peregrine拥有超过180项专利和正在审批的专利，已经向市场提供二十多亿个UltraCMOS。

村田制作所(Murata Manufacturing)全资子公司村田电子(Murata Electronics)于2015年1月，以每股12.5美元的价格，现金收购Peregrine Semiconductor已发行股票，交易总价为4.71亿美元。Peregrine已成为村田制作所的全资子公司，并延续其射频(RF)晶片业务。

Peregrine Semiconductor, a Murata company, is a leading fabless provider of high-performance, radio frequency integrated circuits, or RFICs. The company’s solutions leverage UltraCMOS® technology, a patented, advanced form of silicon on insulator (SOI) that enables the design, manufacture and integration of multiple RF, analog and digital functions onto a single chip. Advancing the performance of RF SOI since 1988, Peregrine today delivers the monolithic integration and superior performance necessary to solve the RF market’s biggest challenges. Peregrine holds more than 280 issued and pending patents and has shipped more than 3.5 billion UltraCMOS units.

UltraCMOS technology combines the ability to achieve the high levels of performance of traditional specialty processes, with the fundamental benefits of standard CMOS, the most widely used semiconductor process technology. Recent product introductions have included state-of-the-art advancements in power limiter devices, a true DC switch delivering performance down to 0 Hz and a high linearity switch that enables a dual upstream and downstream band architecture in cable premises equipment (CPE) devices—allowing CPEs to meet the stringent new requirements of the DOCSIS 3.1 cable industry standard.

Peregrine’s superior linearity, power handling and harmonic performance delivers products that meet the exacting requirements in a broad range of applications in aerospace and defense, broadband, industrial, mobile wireless device, test-and-measurement (T&M) equipment and wireless-infrastructure markets. Peregrine’s products are sold worldwide through direct sales and field applications engineering staff and a network of independent sales representatives and distribution partners.
