PE4259

The PE4259 from pSemi is a Reflective Single-Pole Double-Throw (SPDT) RF Switch that operates from 10 MHz to 3 GHz. It is fabricated using pSemi's UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate. This switch has an insertion loss of less than 0.60 dB and provides more than 19 dB of isolation. It has a switching time of 1.5 µs, a return loss of more than 21 dB, and an input P1dB of 33.5 dBm. This switch supports single-pin or complementary CMOS control-logic inputs with 2 kV HBM ESD tolerance on the RF ports. 

The PE4259 requires a DC supply of 1.8-3.3 V and draws 9 µA of current. This switch is available in a 6-lead SC-70 package measuring 2.05 × 1.25 × 0.90 mm and is supplied in tape-and-reel packaging at 3,000 units per reel.
