50 dB GSM PA Controller

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 dB. It is intended for use in cellular handsets and other batteryoperated wireless devices. The

50 dB GSM PA Controller

FEATURES 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:

Panel interface

The BU8310AK, BU8311KS, and BU8313K are large-scale integrated circuits for telephones, which enable a serial input/output interface between the key input required for telephone panel boards and LED control functions. They reduce the number of wiring harnesses needed between the main board in the
