Overview
The AD8367ARU, produced by Analog Devices Inc., is a high-performance variable gain amplifier designed for use at intermediate frequencies (IF) up to 500 MHz. This device features a 45 dB variable gain range with linear-in-dB gain control, making it suitable for a variety of applications including cellular base stations, broadband access, power amplifier control loops, and complete linear IF AGC amplifiers. The AD8367 utilizes Analog Devices’ proprietary X-AMP™ architecture, which ensures accurate gain control and a wide bandwidth of 500 MHz. The amplifier is fabricated on a high-performance silicon bipolar process and is packaged in a 14-lead thin shrunk small outline (TSSOP) package, fully specified over a temperature range of –40°C to +85°C.
