SW-239 – low-loss, fast GaAs SPDT RF switch

SW-239 is a GaAs MMIC SPDT RF switch designed for low power, low loss signal routing from DC to about 2.5 GHz. Typical insertion loss is around 0.5 dB with isolation near 25 dB, so SW-239 keeps paths clean while crosstalk stays under control. It runs from simple TTL or CMOS control, draws only microwatts of DC power, and sits in a compact SOIC-8 surface-mount package. Use SW-239 for transmit/receive paths, switch matrices, and filter banks in radio, cellular, GPS, and battery powered RF gear. Order SW-239 from Florida Circuit to keep your RF front ends efficient and production-ready.
