ADL5501 - RMS Responding Detector

General Description

The ADL5501 is a mean-responding power detector for use in high frequency receiver and transmitter signal chains from 50 MHz to 4 GHz.

It is easy to apply, requiring only a single supply between 2.7 V and 5.5 V and a power supply decoupling capacitor.

Key Features

  • True rms response Excellent temperature stability Up to 30 dB input dynamic range at 4 GHz 50 Ω input impedance 1.25 V rms, +15 dBm, maximum input Single-supply operation: 2.7 V to 5.5 V Low power: 3 mW at 3 V supply RoHS Compliant 50 MHz to 4 GHz TruPwr™ Detector ADL5501.
