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.

Product Details

AD8314ACP-EVAL is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it requires a 2.7V to 5V/10 mA power supply. The power supply should be connected to the vector pins leads labeled VPOS and GND. The RF input signal is applied to the edge-mounted SMA type RF connector (INPUT). The setpoint input signal is applied to the edge-mounted SMA type connector (VSET). The detector output signals are accessible via the edge-mounted SMA connectors (V_UP, V_DN). The circuit board can accommodate configuration in measurement mode and controller mode depending on the status of jumper (LK1).
