• ADL5910

    Hey everyone,

    I have a quick question, which I can't seem to figure out from the datasheet.

    I need an envelope detector that will cover a wide frequency range as promised by the ADL5910. It needs to follow a signal like this:

    It seems the ADL5910…

  • RE: handling RFpower  with out RF POWER LIMITER

    One option to consider is using a threshold detector which activates a 1-bit digital step attenuator (or even an SPST). Take a look at ADL5910 (www.analog.com/adl5910)

  • RE: How to use ADL5910 peak/envelope eval board to get peak voltages with peak period 1.67 seconds

    Hello boydy33,

    • Is there a RF carrier frequency for your “…spike/pulse of every 1.67 second in signal...” ? You need an input RF signal from the tenth of kHz to 6GHz.  The ADL5910’s TCAL (or VCAL ) pin has a typical output voltage at…
  • RE: Use problem of ADL5910

    1. we do not recommend 5v operation, because it's not a specified vpos for the performance.

    2.RST need to be set high if you ever want to reset the latch.

    3.yes. to clarify, measure VCAL when the circuit trip, and measure VCAL with no RFIN. the difference…

  • ADL5910  , comparator interface behaviour in shutdown.

    In shutdown mode, what is the state of the Q,~Q outputs?  Are these tri-stated (high impedance?)

    This information seems to be missing from the data sheet.

  • Need an envelope detector working at -55C

    Dear Staff and fellows;

    I need an envelope detector working at -55C. My frequency of operation is 60 +/-3 MHz. I was hoping to use ADL5910, but I was guided -by sales representative- as I can not use ADL5910 IC for envelope detection.

    Then the choices…

  • RE: Peak power vs log and envelope detector

    Hello Stefano,

    You are correct about LTC5507 linearity. It would need multi-point calibration.

    Regarding ADL5910, it has digital (comparator) output which would indicate that a specific peak power has been exceeded. Also, the pin 3 VCAL output is available…

  • RF power detector for very small changes in signal

    Hello,

    I am looking for a power detector for measuring shot noise from a tunneling junction. The bandwidth of the shotnoise is between 1Mhz - 5Mhz. When a bias voltage is created between the junction a tunneling current will flow. This current is then…
