Analog Devices’ RMS Power Detector Offers Unparalleled Frequency Performance and Flexibility

The ADL5906 RF detector is well-suited for a variety of applications that require an accurate RMS measurement of signal power including communications infrastructure, power amplifier linearization, Point-to-Point and Point-to-MultiPoint, cable, military, satellite, instrumentation equipment and ISM band transmitters.

Requiring only a single supply of 5V and a few capacitors, the new ADL5906 power detector is easy-to-use and capable of being driven with a single-ended or differential input drive. Furthermore, the ADL5906 provides low temperature drift across a broad -55ºC to +125ºC that is highly repeatable from part-to-part, thereby reducing design risk and manufacturing costs.

ADL5906 TruPwr RMS Power Detector Key Features:

-Accurate RMS-to-dc conversion from 10 MHz to 10 GHz
-Single-ended ± 1dB detection range: 67 dB at 2140 MHz, no balun or external input matching required
-Response-independent of waveform types such as GSM/CDMA/W-CDMA/TD-SCDMA/WiMAX/LTE
-Linear-in-decibels output, scaled 55 mV/dB at 2140 MHz
-Temperature stability of < ±1 dB from -40°C to +85°C
-Operates from -55°C to +125°C
-Power-down capability to 250 µA
-Pin-compatible with the ADL5902 and AD8363 TruPwr™ detectors

The ADL5906 RF detector can be easily designed with a broad array of ADI’s analog-to-digital converters, including the AD7466 12-bit ADC.
