GENERAL DESCRIPTION
The AD8363 is a true rms responding power detector that can be directly driven with a single-ended 50 Ω source. This feature makes the AD8363 frequency versatile by eliminating the need for a balun or any other form of external input tuning for operation up to 6 GHz.

FEATURES
   Accurate rms-to-dc conversion from 50 Hz to 6 GHz
   Single-ended input dynamic range of >50 dB
   No balun or external input tuning required
   Waveform and modulation independent, such as
      GSM/CDMA/W-CDMA/TD-SCDMA/WiMAX/LTE
   Linear-in-decibels output, scaled: 52 mV/dB
   Log conformance error: <±0.15 dB
   Temperature stability: <±0.5 dB
   Voltage supply range: 4.5 V to 5.5 V
   Operating temperature range: −40°C to +125°C
   Power-down capability to 1.5 mW
   Small footprint, 4 mm × 4 mm, LFCSP

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