Peregrine Semiconductor SP4T RF Switch Achieves Best-in-Class Linearity

"We continue to push the limits of our RFIC portfolio, achieving performance with UltraCMOS that cannot be matched with GaAs-based and other SOI devices," said Mark Schrepferman, director of the communications and industrial product line at Peregrine. "No other SP4T RF switch on the market can deliver the broad combination of exceptional features found in this device, making it ideal for many general purpose RF applications entering the market today," he added. "When you add all the environmental benefits of SOS, it's clear that UltraCMOS is the IC-of-choice over GaAs-based devices and the growing concerns about toxic e-Waste," he concluded.

The new reflective PE42440 switch delivers market-leading RF performance unmatched by its competition: an IIP3 of +67 dBm and P1dB of 41.5 dBm (across the range); Insertion Loss of 0.45 dB; and very high Isolation of 34 dB (at 1 GHz). The 50-Ohm switch handles maximum +33 dBm input power (500 MHz to 3 GHz) with world-class ESD tolerance of 4.0 kV HBM on the RFC pin. Additional features include integrated CMOS control logic, decoder for 2-pin control that accepts 1.8V and 2.75V control logic levels, and a low 4.5 Ohm series ON resistance. A single Vdd supply pin eliminates the need for multiple power supplies and power up sequencing which is typically required on competitive devices. As with all SOS-based UltraCMOS RFICs, the device settles fast without gate lag or insertion loss drift, and no blocking capacitors are required.

The PE42440, packaged in the 16-lead 3mmx3mm QFN, is available in volume today and is priced at $0.67 each (100K units).

About Environmentally-friendly UltraCMOS Technology

UltraCMOS mixed-signal process technology is a patented advancement of silicon-on-insulator (SOI) technology on a sapphire substrate providing high yields, competitive costs and a "green" alternative to GaAs-based technologies. UltraCMOS delivers significant performance advantages over competing processes such as GaAs, SiGe BiCMOS and bulk silicon CMOS in applications where RF performance, low power and high levels of integration are paramount. These measureable power and size savings offer advantages for both manufacturers and consumers, including longer battery life, smaller batteries, lower power consumption and bills, less electronic waste...and a greener Earth. Further, the company's revolutionary HaRP and DuNE technologies further exploit the fundamental benefits of silicon-on-sapphire, enabling dramatic improvements in harmonic results, linearity, power handling and overall RF performance which today remain unmatched by any other RF process technology.
