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. The excellent distortion performance and low noise characteristics of this device allow for a wide range of applications.
