• RE: AD8362 27MHz slope and intercept

    There is good description of a typical calibration process on page 24 of the ADL5906 datasheet (rev A). It's called System Calibration and Error Calculation.  ADL5906 and AD8362 are functionally almost identical so the equations described in there…

  • RE: Composite Power Detector and Envelope Detector Response Time

    I don't have a HMC1020 or HMC1120 at hand but I did perform the following test on the ADL5906 which is a similar device.


    1. I used the ADL5906 rms detector for this test. 
    2. I set up two signal generators, one at 200 MHz and one at 1 GHz (both CW…
  • ADL5906 output voltage issue


    as you can see on the following schematic my ADL5906ACPZ#1428 is the very similar configuration like it is on the evaluation Board.

    Without an input signal I have an output voltage of 1V to 1,4V. (vary with the ADL5906 IC)

    Even if I connect…

  • EVAL-ADL5906 trouble with test

    good day,

    I have a eval-adl5906 board, I connect to the pos pin 5V (and GND pin) and connect  the antenna to rfin pin but when i measure in vout pin the voltage is:

    1v in 1Ghz and 0.6 in 10Ghz; I have no voltage in the range of datasheet.

    for test…

  • RE: ADL5920 Crest factor

    There is no real limit on the crest factor when using ADL5920. What you will find is that there will be a increasing measurement error for signals which have a large crest factor. The rms detector used in ADL5920 is very similar to ADL5906. In the ADL5906…

  • RE: ADL5906  - Output Voltage without the Input Signal


    We followed the same solution mentioned by   in ADL5906 output voltage issue

    Now, the voltage is 0.052V for no input signal.

    Thanks to and

  • RE: ADL5902 at low frequencies

    On ADL5902, there is no access to the CHPF cap. So it's not possible to extend the operating frequency range downwards like you are doing with AD8363. So that is the main limiting factor. The signal path on the device is also ac-coupled internally. So…

  • Pulse Response of Linear-in-dB RMS Detectors with no RMS Averaging Capacitor Present

    Question: RMS detectors with a Linear-in-dB transfer function such as AD8362, AD8363, AD8364, ADL5902 and ADL5906 produces a peaking in detection voltage when driven by RF Bursts when there is no rms averaging capacitor present.  Adding an external rms…

  • RE: Queries about ADL5902’s Response Time and Noise

    Figure 48 shows the relationship between rise and fall time and output noise. However, the signal being used here is a 3G WCDMA signal with a bandwidth of 3.84 MHz. You can see from this plot that a filter cap of just over 10nF will give you 50mVpp of…

  • S-Paramters for a RMS-responding RF Detectors

    Question: Are S-Parameters available rms-responding RF detectors such as AD8362 or ADL5902? Or is there some kind of a behavioral model available for these devices.

    Answer: We do not publish s-parameters for rf detectors. It is not really meaningful…
