Analog Devices Unveils Wide-Dynamic-Range, Highly Accurate RF Power Detectors

Analog Devices, Inc. (ADI), a world leader in high-performance semiconductors for signal processing applications, today introduced two RF power detectors with wide dynamic range and best-in-class accuracy and temperature stability. Designed with ADI’s leading detector expertise, the ADL5903 RF detector is an optimal solution for a variety of high frequency systems requiring accurate measurement of signal power independent of waveform characteristics. The ADL5506 RF detector is a complete subsystem for the measurement of RF signals in a wide range of wireless terminal devices. Both detectors are offered in small packages with low-power operation, making them ideal for designs that are constrained by space or power.

ADL5903 Key Features:
  • Single-ended input dynamic range of 35 dB, 50 Ω source-compatible
  • Accurate RMS-to-DC conversion from 200 MHz to 6 GHz
  • Linear in decibels output, scaled 35.5 mV/dB at 900 MHz
  • Waveform and modulation independent

ADL5506 Key Features:
  • Typical dynamic range: 45 dBm to 0 dBm
  • Frequency range from 30 MHz to 4.5 GHz
  • Stable linear-in decibel response
  • Low power: 3.8mA @ 3 V (with < 1uA in Disable Mode)

Pricing, Availability, Packaging and Complementary Products
Product       Samples       Production       Pricing Each Per 1,000       Package

ADL5903
      Now       Now       $2.35       8-lead LFCSP

ADL5506
      Now       Now       $1.27       6-ball WLCSP

The new RF detectors can be easily designed with a variety of analog-to-digital converters such as the AD7920 and AD7466 to digitize the measurement output, and the ADL5506 works well with the ADL5330 and ADL5331 VGAs for implementation of power control loops.
