Digi-Key Corporation and Peregrine Semiconductor Ink Global Distribution Agreement

THIEF RIVER FALLS, Minnesota, USA - May 5, 2011

Electronic components distributor Digi-Key Corporation, recognized by design engineers as having the industry's broadest selection of electronic components available for immediate shipment,and radio frequency integrated circuit (RFIC) manufacturer Peregrine Semiconductor today announced the two companies have finalized a global distribution agreement involving Peregrine's UltraCMOS™ RFIC products.

A number of Peregrine's most popular RF ICs—RF switches, digital step attenuators, PLL frequency synthesizers, mixers and prescalers—are now available for purchase on Digi-Key's global websites.

Peregrine Semiconductor is a fabless supplier of high-performance RFICs which leverage its proprietary UltraCMOS technology, enabling the design, manufacture, and integration of multiple RF, mixed-signal, and digital functions on a single chip. Peregrine's products target a broad range of applications in the aerospace and defense, broadband, industrial, mobile wireless device, test and measurement equipment, and wireless infrastructure markets.

"We are excited to announce the addition of Peregrine's innovative UltraCMOS silicon-on-sapphire (SOS) RFIC solutions to Digi-Key's vast product listing," said Mark Zack, Digi-Key's vice president of semiconductor product. "Our goal is to provide the best products from antenna in to data out and we believe Peregrine's advanced technology will help us achieve that goal."

"OEM engineering teams designing tomorrow's wireless products are increasingly faced with complex RF integration challenges, and they need simple solutions, fast," said Dale Robinette, Peregrine's director of worldwide sales. "Peregrine continues to drive its growth by accessing new customers in all parts the world; adding Digi-Key to our channel partner strategy broadens our reach to this audience, expands our sales support capability, and ultimately puts our product closer to the customer. We look forward to our combined strength in the marketplace."

About Peregrine Semiconductor

Peregrine Semiconductor is a fabless provider of high performance radio frequency integrated circuits, or RFICs. Our solutions leverage our proprietary UltraCMOS™ technology, which enables the design, manufacture, and integration of multiple RF, mixed-signal, and digital functions on a single chip. Our products deliver what we believe is an industry leading combination of performance and monolithic integration, and target a broad range of applications in the aerospace and defense, broadband, industrial, mobile wireless device, test and measurement equipment, and wireless infrastructure markets. 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. UltraCMOS technology utilizes a synthetic sapphire substrate, a near-perfect electrical insulator, providing low parasitic capacitance and enabling high signal isolation and excellent broadband linearity. These attributes result in RF devices with excellent high-frequency performance and power handling performance, reduced crosstalk between frequencies, and enhanced network efficiency. We have engineered design advancements, including our patented HaRP™ technology which significantly improves harmonic and linearity performance, and our patent-pending DuNE™ technology, a circuit design technique that we have used to develop our advanced digitally tunable capacitor (DTC) products. We offer a broad portfolio of high performance RFICs including switches, digital attenuators, frequency synthesizers, mixers and prescalers, and are developing power amplifiers (PAs), DTCs, and DC-DC converters. Our products are sold worldwide through our direct sales and field applications engineering staff and our network of independent sales representatives and distribution partners.
