AD8311: 50 dB GSM PA Controller
Product 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 - 2.5 GHz and over a typical dynamic range of 50 dB. It is intended for use in cellular handsets and other battery-operated wireless devices. The log amp technique provides a much wider measurement range and better accuracy than controllers using diode detectors. In particular, its temperature stability is excellent over a specified range of -40°C to +85°C.
Its high sensitivity allows control at low signal levels, thus reducing the amount of power that needs to be coupled to the detector.
