• ADL5502 is a photosensible device?

    What is the reason to define the "light condition"(<= 600lux) on Typical Performance Characteristics as reported at page 8 of datasheet?

  • The two ADL5502-EVALZ boards have different behaviors.

    The two ADL5502-EVALZ boards have different behaviors.

    We tested the behavior after purchasing 2 ADL5502-EVALZ boards about two weeks ago.

    One board (A) seems to be working normally.

    However, the other board (B) has an output of about 400mV, regardless…

  • ADL5502 peak detect for ultrashort pulse measurement

    Hello everybody,

    A femtosecond laser pulse generates an electrical pulse on a photodiode.

    Pulse is gaussian like with a FWHM of 590ps thanks to the rise time of the PD (175ps) - this means a Bandwith of up to 2GHz

    The ADL5502 is used for RMS and peak…

  • ADL5502 Low Frequency Operation

    ADL5502 has a low frequency boundary of 450 MHz according to the datasheet. What would be the issues if I operate it around 100MHz? Any hint?

  • ADL5502 peak hold time on the datasheet


    I have question about ADL5502 datasheet P5 "Peak Hold time".

    The datasheet has Peak Hole Time.

    In this section has "CNTL=high". For peak hold, CNTL should be "Low".


    How should I understand the explanation?

  • RE: analog signal processing


    Analog Devices has quite a few rms RF power detectors to choose from. Some have comparator function built-in. Maybe the system MCU could take periodic measurements, send that out to a DAC which sets the comparator threshold, then go to sleep and…

  • FAQ: RF Detector Recommendations


    We are currently using the AD8361 and are currently going through a redesign.  We are looking for less temperature variation and better rms accuracy (i.e. waveform independence or the deviation from CW).  What are your recommendations?


  • RF peak detector


    I'm looking for an RF peak detector in the 200-600 MHz frequency range. (whit hold and reset functions)

    The ADL5502 device would have all the needed functionalities, however the lowest input frequency is only 450 MHz.

    Do you have any suggestion…

  • RF Power meter for 5G RU


    My company has so far used "ADL5502" for LTE small cell output power detection.

    Now, for our new 5G RU design we are searching for a part number compatible with 5G requirements. So far we have found "ADL5511" as the compatible version for…

  • RE: true RMS power detection resolution

    This subject has been partially addressed in another thread:


    Regarding which RMS power detector is best:
