The ADG901/ADG902 is a dual-path switch that operates up to 4.5 GHz and uses a CMOS process for high isolation and low insertion loss.
The ADG901 (absorptive) and ADG902 (reflective) are wideband CMOS SPST switches offering high off‑state isolation and low insertion loss up to 1 GHz. They operate from a single 1.65 V to 2.75 V supply and are available in 8‑lead MSOP and 3 mm × 3 mm LFCSP packages.
These devices are suited for wireless communications, RF switching, antenna diversity, and high‑speed filter selection. Key performance figures include 40 dB off isolation and 0.8 dB insertion loss at 1 GHz, with typical power consumption below 1 pA.
