AD8312 Datasheet PDF

Analog Devices AD8312

The AD8312 is a complete, low cost subsystem for the measurement of radio frequency (RF) signals in the frequency range of 50 MHz to 3.5 GHz. It has a typical dynamic range of 45 dB and is 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.
