Overview
The AD608AR, produced by Analog Devices Inc., is a low power, low distortion, and low noise mixer/limiter/RSSI (Received Signal Strength Indicator) subsystem. It is designed for use in various wireless communication systems, including PHS, GSM, TDMA, FM, and PM receivers. This device integrates a doubly balanced Gilbert-cell mixer, a logarithmic/limiting amplifier, and an RSSI output, making it a comprehensive solution for IF (Intermediate Frequency) signal processing. The AD608 operates on a single supply voltage ranging from 2.7 V to 5.5 V and is known for its high performance, low power consumption, and compact 16-lead SOIC package.
