Peregrine Semiconductor Corp. (Peregrine) announced from booth # 2009 at the International Microwave Symposium (IMS2012) in Montreal, the SP3T PE42430 RF switch. Developed on Peregrine’s patented UltraCMOS® technology, the PE42430 switch combines low insertion loss with high linearity, high isolation, and small package size, making it well suited for WLAN and Bluetooth® applications in the 2.4 GHz band, as well as general broadband switching applications. An on-chip CMOS decode logic facilitates a three-pin CMOS control interface and, because VDDis derived from switch-control inputs, there is no need for a VDDpin.

Peregrine’s HaRP™ technology enhancements enable excellent IIP3 linearity of 66 dBm in the PE42430 device—the Company’s first SP3T RF switch. This switch features low insertion loss of 0.45 dB @ 1GHz and 0.55 dB @ 2.5 GHz, and high isolation of 40 dB @ 1 GHz and 30 dB @ 2.5 GHz. Additionally, it provides excellent ESD tolerance of 4500V HBM and 250V MM on all ports, and is available in a miniature, 8-lead 1.5 mm x 1.5 mm DFN package.

“Engineers are constantly working to improve the performance of their designs, while reducing the size and overall component count,” said Mark Schrepferman, director of marketing for Peregrine’s High-Performance Solutions business unit. “With its combination of low insertion loss, high linearity and high isolation in a tiny package, the PE42430 switch addresses these needs.”

Packaging, Pricing & Availability

            The PE42430 switch is available in an 8-lead, 1.5 mm x 1.5 mm DFN package, for $0.69 each, in 10,000-unit quantities. Samples and volume-production quantities can be ordered today, through Peregrine’s global direct sales representatives. For more information, visit
