GENERAL DESCRIPTION
The ADL5511 is an RF envelope and TruPwr™ rms detector. The envelope output voltage is presented as a voltage that is proportional to the envelope of the input signal. The rms output voltage is independent of the peak-to-average ratio of the input signal.

FEATURES
   Envelope tracking RF detector with output proportional to
      input voltage
   Separate TruPwr rms output
   No balun or external tuning required
   Excellent temperature stability
   Input power dynamic range of 47 dB
   Input frequency range from dc to 6 GHz
   130 MHz envelope bandwidth
   Envelope delay: 2 ns
   Single-supply operation: 4.75 V to 5.25 V
   Supply current: 21.5 mA
   Power-down mode: 130 µW

APPLICATIONS
   RMS power and envelope detection of W-CDMA, CDMA2000,
      LTE, and other complex waveforms
   Drain modulation based power amplifier linearization
   Power amplifier linearization employing envelope-tracking
