The SPDTPE42421 RF switch from Peregrine Semiconductor Corp. is available in a miniature six-lead SC-70 package. It offers a strong electrostatic discharge (ESD) performance of 2 kV on the RFC port, low voltage support down to 1.8- voltage drain drain (Vdd), and low power consumption of nine microamperes (typ). With these attributes and its small package size, the new switch is suitable for 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 50 dBm IIP3 and on-chip, low-voltage complementary metal oxide semiconductor control logic. It can be controlled using either single-pin or complementary-control inputs.
