AD8315ARMZ-RL General Description

The AD8315 is a complete low cost subsystem for the precisecontrol of RF power amplifiers operating in the frequency range0.1 GHz to 2.5 GHz and over a typical dynamic range of 50 dB.It is intended for use in cellular handsets and other batteryoperatedwireless devices. The log amp technique provides a muchwider measurement range and better accuracy than controllersusing diode detectors. In particular, the temperature stability isexcellent over a specified range of −30°C to +85°C.

Key Features

>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

Application

Single, dual, and triple band mobile handset (GSM, DCS, EDGE)
Transmitter power control
