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

Dec 16 2013 - Norwood, MA
  • 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:

    • Ripple free linear in dB dynamic range: 45 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

     Part Number  Samples  Production  Pricing (1Ku quantities)  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.
