GENERAL DESCRIPTION
The AD8363 is a true RMS responding power detector that has more than 50 dB measurement range when driven with a single-ended 50 Ω source. The device provides a solution in a variety of high frequency communication systems, and in instrumentation, requiring an accurate response to signal power. The AD8363 is easy to use with its single-ended 50 Ω input, only requiring a single 5 V supply, and a few capacitors. The AD8363 can operate from arbitrarily low frequencies to 6 GHz and can accept inputs that have RMS values from less than -50 dBm to at least 0 dBm, with large crest factors, exceeding the requirements for accurate measurement of WiMAX, WCDMA, and CDMA signals.

FEATURES
   Accurate RMS-to-DC conversion from 50 Hz to 6 GHz
   Single ended input dynamic range of >50 dB
   Waveform and modulation independent, such as
      WiMAX/GSM/CDMA/WCDMA/TDMA
   Linear-in-decibels output, scaled 50 mV/dB
   Log conformance error of <0.3 dB
   Temperature stability of <±0.5 dB
   Voltage supply range of 4.5 V to 5.5 V
   Operating temperature range of −40°C to +125°C
   Power-down capability

APPLICATIONS
   Power amplifier linearization/control loops
   Transmitter power controls
   Transmitter signal strength indication (TSSI)
   RF instrumentation
