Peregrine unveils SPDT RF switch in SC-70 package for battery-powered and automotive-telematics applications
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 launched the SPDT PE42421 RF switch, available in a miniature, 6-lead SC-70 package. The firm claims that, with its small package size, strong ESD performance of 2kV on the RFC port, low-voltage support down to 1.8V VDD, and low power consumption of 9 microamperes (typical), the new switch is suited to battery-powered portable applications, as well as automotive-telematics applications, such as vehicle entry systems and emergency calls.
The 50 Ohm, reflective UltraCMOS PE42421 switch features high linearity of 50dBm IIP3 and on-chip, low-voltage CMOS control logic. It can be controlled using either single-pin or complementary-control inputs. The switch also features low insertion loss of 0.35dB at 1.0GHz and 0.50dB at 2.0GHz, with high isolation of 30dB at 1GHz and 20dB at 2GHz. Using a nominal +3V power-supply voltage, a typical input 1dB compression point of +33.5dBm can be achieved.
“Customers continue to push for low-power and high-ESD performance in the smallest package size possible, in order to deliver optimal RF performance in their portable device and automotive-telematics designs,” comments Mark Schrepferman, director of marketing for Peregrine’s high-performance solutions business unit. “The PE42421 switch meets these needs, and also makes customers' manufacturing processes more reliable,” he claims.
The PE42421 switch is available for $0.30 each, in 10,000-unit quantities. Peregrine has also announced the PE42421 Evaluation Kit (part number EK42421-01). The kit includes a USB interface board and cable, and is priced at $95.
