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.
