SPDT RF switch suits battery-powered and automotive telematics applications
Peregrine Semiconductor announced the availability of the SPDT PE42421 RF switch, which is available in a miniature, six-lead SC-70 package. With its small package size, ESD performance of 2 kV on the RFC port, low voltage support down to 1.8V VDD, and low power consumption of 9 microamperes (typ.), the new switch is well suited 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 CMOS control logic. It can be controlled using either single-pin or complementary-control inputs. Additionally, the switch features low insertion loss of 0.35 dB at 1.0 GHz and 0.50 dB at 2.0 GHz, with high isolation of 30 dB at 1 GHz and 20 dB at 2 GHz. Using a nominal +3V power-supply voltage, a typical input 1 dB compression point of +33.5 dBm can be achieved. The PE42421 switch is available in a 6-lead SC-70 package for $0.30 each, in 10,000-unit quantities.
