AD8352 Rev. B is a 2 GHz ultralow distortion differential RF/IF amplifier with a 3 dB bandwidth of 2.2 GHz (AV = 10 dB), single resistor gain adjust, single resistor and capacitor distortion adjust, differential or single-ended input to differential output, low noise input stage, low broadband distortion, OIP3 of 41 dBm @ 150 MHz, fast settling and overdrive recovery time less than 2 ns, single-supply operation 3 V to 5.5 V, low power dissipation 37 mA typical @ 5 V, power-down capability 5 mA @ 5 V, fabricated using the high speed XFCB3 SiGe process.
The AD8352 is a high‑performance differential RF/IF amplifier optimized for wideband, low‑distortion operation up to 2 GHz. It features a constant 3 kΩ input resistance, low‑noise input stage (2.7 nV/√Hz), 8 V/ns slew rate, and OIP3 of 41 dBm at 150 MHz.
Typical applications include RF/IF gain blocks, SAW‑filter interfacing, and driving high‑speed ADCs, mixers, and pin‑diode attenuators. The device is offered in a 3 mm × 3 mm 16‑lead LFCSP package and operates from 3 V to 5.5 V over –40 °C to +85 °C.
