2.5 GHz TruPwr™ Detector
The AD8361 is a TruPwr™ Detection RFIC, offering RMS-responding power detection for the first time in integrated form. The device is capable of converting a complex modulated RF signal, from up to 2.5 GHz, into a DC voltage representing the RMS level of the signal. The device is highly linear and temperature stable. It is useful for detection of CDMA, QAM and other complex modulation schemes.
The dynamic range is 30 dB. Measurement accuracy is 0.25 dB over a 14 dB range and 1 dB over a 23 dB range. The AD8361 is offered in a small 8-pin micro-SO package and requires only 4 mA from a 2.7 to 5.5 V power supply.
An evaluation board is available for this product and may be ordered using the following product number: AD8361-EVAL. Schematic and layout for this evaluation board are contained in the product datasheet.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
AD8361-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it requires a 2.7 V to 5 V/15 mA power supply. The power supply should be connected to the vector pins labeled VPOS and GND. The RF input signal is applied to the edge-mounted SMA type RF connector (RFIN). The RMS output signal is accessible via the edge-mounted SMA connector (VRMS).
