LF to 2.7 GHz, DUAL 60 dB TruPwr™ Detector
The AD8364 is a dual channel TruPwr™ detector, designed to provide wide dynamic range signal power measurement (> 60dB). The product provides an accurately scaled linear-in-dB output response, that is the equivalent Root-Mean-Square (RMS) of the input waveform.
The AD8364 integrates two matched individual channels on a single IC, enabling three RMS output voltages, an accurately scaled independent output for each input channel and a difference output that can measure the gain or loss between the two input signals. In addition to the RMS outputs, the AD8364 provides an output voltage proportional to temperature from on chip temperature sensor.
The AD8364 is ideally suited for the measurement of complex modulated waveforms, with large crest factors. The AD8364 is effectively waveform and modulation independent enabling the user to acquire a precise RMS level of complex modulated (QAM / QPSK / OFDM) wavefoms found high capacity wireless and wire-line communication networks. More detailed information on the CDMA and W-CDMA power measurements is shown within the product data sheet.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
AD8364-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it requires a 5 V/100 mA power supply. The 5 V power supply should be connected to the clip leads labeled VPS and COMM1. The two RF input signals are applied to two edge-mounted SMA type RF connectors. The output signals are accessible via the OUTA, OUTB, OUTN, OUTP and TEMP clip leads. The circuit board can also accommodate 6-pin and 26-pin headers through which the power supply, ground, temperature adjust nodes and output signal pins are accessible (the circuit board ships with these headers not installed).
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
