The PE42521 SPDT absorptive RF switch is designed for use in test/ATE and other high performance wireless applications. This broadband general purpose switch maintains excellent RF performance and linearity from 9 kHz through 13 GHz. This switch is a pin-compatible upgraded version of PE42552 with fast switching time and higher power handling of 36 dBm continuous wave (CW) and 38.5 dBm instantaneous power in 50Ω @ 4 GHz. The PE42521 exhibits high isolation, fast settling time, and is offered in a 3×3 mm QFN package. The PE42521 is manufactured on pSemi’s UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
