100 MHz To 2.7 GHz, 45 DB RF Detector/Controller
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 -40C to +85C.
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 A.
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.
