Analog Devices Inc. (ADI), a world leader in high-performance semiconductors for signal processing applications and RF ICs, introduced a high performance RMS power detector. Featuring operation up to 10 GHz and a 67 dB measurement range, the ADL5906 TruPwr™ RMS detector is frequency versatile and eliminates the need for external input tuning devices, such as a balun. 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 -55º 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° to +85°C
  • Operates from -55° to +125°C
  • Power-down capability to 250 µA
  • Pin-compatible with the ADL5902 and AD8363 TruPwr™ detectors
