Product Summary

The AD8314ARM is a RF Detector/Controller in the frequency range 0.1 GHz–2.5 GHz, with a typical dynamic range of 45 dB, intended for use in a wide variety of cellular handsets and other wireless devices. The AD8314ARM provides a wider dynamic range and better accuracy than possible using discrete diode detectors. The AD8314ARM provides two voltage outputs. The first, called V_UP, increases from close to ground to about 1.2 V as the input signal level increases from 1.25 mV to 224 mV. This output is intended for use in measurement mode. A capacitor may be connected between the V_UP and FLTR pins when it is desirable to increase the time interval over which averaging of the input waveform occurs.
