AD603SQ/883BQ

Product Overview

AD603SQ_883BQ is commonly associated with Analog Devices AD603SQ/883B, a low-noise voltage-controlled variable gain amplifier designed for RF, IF and automatic gain control applications. The device provides accurate linear-in-dB gain control with pin-selectable gain ranges, supporting -11dB to +31dB operation at 90MHz bandwidth or +9dB to +51dB operation at 9MHz bandwidth. With low input-referred noise, military-grade screening option and 8-CERDIP package, it is suitable for radar receivers, communication systems, instrumentation, AGC loops and high-reliability analog signal processing designs.
