AD8314:  RF Detector / Controller, 100 MHz TO 2.7 GHz, 45 dB

Product Details


The AD8314 is a complete low cost subsystem for the measurement and control of RF signals in the frequency range of 100 MHz 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.

The AD8314 is available in 8-lead MSOP and 8-lead LFCSP packages and consumes 4.5 mA from a 2.7 V to 5.5 V supply. When powered down, the typical sleep current is 20 µA.

An evaluation board is available for this product and may be ordered using the following product number: AD8314-EVAL. Schematic and layout for this evaluation board is contained in the product datasheet.
