Product Specification PE42821 UltraCMOS SPDT RF Switch 100 - 2700 MHz Product Description Features The PE42821 is a HaRP technology-enhanced high power reflective SPDT RF switch designed for use in High power handling mobile radio, relay replacement and other high 45 dBm 850 MHz, 32W performance wireless applications. 44 dBm 2 GHz, 25W High linearity This switch is a pin-compatible faster switching version of 82 dBm IIP3 850 MHz the PE42820. It maintains high linearity and power 76 dBm IIP3 2.7 GHz handling from 100 MHz through 2.7 GHz. PE42821 also Low insertion loss features low insertion loss and is offered in a 32-lead 0.35 dB 850 MHz 5x5 mm QFN package. In addition, no external blocking 0.60 dB 2 GHz capacitors are required if 0V DC is present on the RF Fast switching time of 4 s ports. (bypass mode) Wide supply range of 2.3V to 5.5V The PE42821 is manufactured on Peregrines UltraCMOS process, a patented variation of silicon-on- +1.8V control logic compatible insulator (SOI) technology on a sapphire substrate. ESD performance 1.5kV HBM on all pins Peregrines HaRP technology enhancements deliver External negative supply option high linearity and excellent harmonics performance. It is an innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS. Figure 2. Package Type 32-lead 5x5 mm QFN Figure 1.
