Overview
The AD8350AR20, produced by Analog Devices Inc., is a high-performance fully-differential amplifier designed for use in RF and IF circuits up to 1000 MHz. This amplifier is renowned for its excellent noise figure of 5.9 dB at 250 MHz and a high output third-order intercept (OIP3) of +28 dBm at 250 MHz. It is available in two gain versions: 15 dB (AD8350-15) and 20 dB (AD8350-20). The AD8350 series is fabricated using Analog Devices’ proprietary high-speed complementary bipolar process, ensuring exceptional linearity, high dynamic range, and increased common-mode rejection. The device is suitable for a variety of applications, including cellular base stations, communications receivers, and high-speed data transmission.
