AD608 is a low power mixer/limiter/RSSI 3V receiver IF subsystem
The AD608 is an integrated circuit combining a low distortion, low noise doubly-balanced Gilbert-Cell mixer with a complete monolithic logarithmic/limiting amplifier. It utilizes a successive-detection technique to provide a high-speed RSSI output and a hard-limited signal output.
Designed for applications such as PHS, GSM, TDMA, FM, or PM receivers, the device operates from a single 2.7 V to 5.5 V supply with typical power consumption of 21 mW at 3 V. It features an onboard LO preamplifier and is specified for industrial temperature ranges.
