AD8351 - Low Distortion Differential RF/IF Amplifier

General Description

The AD8351 is a low cost differential amplifier useful in RF and IF applications up to 2.2 GHz.

The voltage gain can be set from unity to 26 dB using a single external gain resistor.

The AD8351 provides a nominal 150 Ω differential output impedance.

Key Features

  • 3 dB bandwidth of 2.2 GHz for AV = 12 dB Single resistor programmable gain: 0 dB ≤ AV ≤ 26 dB Differential interface Low noise input stage 2.7 nV/√Hz at AV = 10 dB Low harmonic distortion.
  • 79 dBc second at 70 MHz.
  • 81 dBc third at 70 MHz OIP3 of 31 dBm at 70 MHz Single-supply operation: 3 V to 5.5 V Low power dissipation: 28 mA at 5 V Adjustable output common-mode voltage Fast settling and overdrive recovery Slew rate of 13,000 V/μs Power-down capability.
