Description

This is Logarithmic Detector/Controller. Data Sheet 0.1 GH- to 2.5 GH- 70 dB Logarithmic Detector, Controller AD8313 01085-C-001 FEATURES Wide bandwidth: 0.1 GH- to 2.5 GH- min High dynamic range: 70 dB to ±3.0 dB High accuracy: ±1.0 dB over 65 dB range (@ 1.9 GHz) Fast response: 40 ns full-scale typical Controller mode with error output Scaling stable over supply and temperature Wide supply range: 2.7 V to 5.5 V Low power: 40 mW at 3 V Power-down feature: 60 mW at 3 V Complete and easy to use APPLICATIONS RF transmitter power amplifier setpoint control and level monitoring Logarithmic amplifier for RSSI measurement cellular base stations, radio link, radar GENERAL DESCRIPTION The AD8313 is a complete multistage demodulating logarithmic amplifier that can accurately convert an RF signal at its input to an equivalent decibel-scaled value at its dc output. The AD8313 maintains a high degree of log conformance for signal frequencies from 0.1 GH- to 2.5 GHz. Application is straightforward, requiring only a single supply of 2..
