Peregrine announces low-insertion-loss SP3T RF switch

Peregrine Semiconductor Corp of San Diego, CA, USA, a fabless provider of radio-frequency (RF) integrated circuits (ICs) based on silicon-on-sapphire (SOS), has introduced its SP3T PE42430 RF switch.

Developed on Peregrine’s patented UltraCMOS technology, the PE42430 combines low insertion loss with high linearity, high isolation, and small package size, making it suitable 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 VDD is derived from switch-control inputs, there is no need for a VDD pin.

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

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