The AD8311 is a complete low cost subsystem for the precise control of RF power amplifiers operating in the frequency range 0.1 GHz to 2.5 GHz and over a typical dynamic range of 50 dB. It is intended for use in cellular handsets and other batteryoperated wireless devices. The log amp technique provides a much wider measurement range and better accuracy than.
Complete RF detector/controller function >50 dB range at 0.9 GHz (−48 dBm to +3 dBm re 50 Ω) Accurate scaling from 0.1 GHz to 2.5 GHz Temperature-stable linear-in-dB response Log slope of 23 mV/dB, intercept at −60 dBm at 0.9 GHz True integration function in control loop Low power: 20 mW at 2.7 V APPLICATIONS Single, dual, and triple band mobile handset (GSM, DCS, EDGE) Transmitter power control GENERAL DESCRIPTION The AD8311 is a complete low cost subsystem for the precise control of RF power amplifiers operating in the frequency range 0.1 GHz to 2.5 GHz and over a typical dynamic range of 50.
