AD8312 Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The AD8312 is a complete, low cost subsystem for the measurement ofRF signals in the frequency range of50 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. In particular, its temperature stability is excellent over the fulloperating range of −40°C to+85°C.
