Description

This is RF Detector/Controller. 100 MH- to 2.7 GHz, 45 dB RF Detector, Controller AD8314 FEATURES Complete RF detector, controller function Typical range: 58 dBV to 13 dBV 45 dBm to 0 dBm, re 50 Ω Frequency response from 100 MH- to 2.7 GH- Temperature-stable linear-in-dB response Accurate to 2.7 GH- Rapid response: 70 ns to a 10 dB step Low power: 12 mW at 2.7 V Power down to 20 μA APPLICATIONS Cellular handsets (TDMA, CDMA , GSM) RSSI and TSSI for wireless terminal devices Transmitter power measurement and control GENERAL DESCRIPTION The AD8314 is a complete low cost subsystem for the measurement and control of RF signals in the frequency range of 100 MH- to 2.7 GHz, with a typical dynamic range of 45 dB, intended for use in a wide variety of cellular handsets and other wireless devices. It provides a wider dynamic range and better accuracy than possible using discrete diode detectors. In particular, its temperature stability is excellent over the full operating range of 40°C to +85°C. Its high sensiti.
