AD8315 - 50 dB GSM PA Controller

General Description

The AD8315 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.

Key Features

  • Complete RF detector/controller function >50 dB range at 0.9 GHz (.
  • 49 dBm to +2 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, 38 mW at 5 V Power-down to 10.8 μW.
