Peregrine PE42822 SPDT switch

The PE42822 is a an absorptive 50 Ω SPDT RF protection switch designed for use in high-power and high-performance wireless infrastructure and small cell applications, supporting frequencies up to 3800 MHz.

The switch features high linearity, which remains invariant across the full supply range, as well as good isolation and fast switching time. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports.

The product is manufactured on Peregrine’s UltraCMOS process, a variation of silicon-on-insulator (SOI) technology on a sapphire substrate. The company’s HaRP technology enhancements deliver high linearity and good harmonics performance. It is an innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS.

Additional key features include: single-event peak power handling of 46.1 dBm LTE; input IP3 of 65 dBm; input IP2 of 120 dBm; extended operating temperature of 105°C; 1.8/3.3 V TTL compatible control; ESD performance of 3 kV HBM on RF pins to ground.
