Product Summary

The AD8369ARUZ is a high performance digitally controlled variable gain amplifier (VGA) for use from low frequencies to a -3dB frequency of 600 MHz at all gain codes. The AD8369ARUZ delivers excellent distortion performance: the two-tone, third-order intermodulation distortion is –69 dBc at 70 MHz for a 1 V p-p composite output into a 1 kW load. The AD8369ARUZ has a nominal noise figure of 7 dB when at maximum gain, then increases with decreasing gain. Output IP3 is +19.5 dBm at 70 MHz into a 1 kW load and remains fairly constant over the gain range. The applications of the AD8369ARUZ include Cellular/PCS Base Stations, IF Sampling Receivers, Fixed Wireless Access, Wireline Modems and Instrumentation.
