• RE: ADF41513 (PLL) + HMC8364 HMC

    Hi Nikolaos,

    Some frequency drift can be normal dependent on the measurement setup. To try to completely eliminate any drift and get a sub-Hertz accurate measurement you would need to setup the ADF41513 eval board to accept an external REFIN (please see…

  • Gerbers for EVAL-ADF41513


    Do you have design files/Gerbers available for the EVAL-ADF41513? I've looked through the product pages and didn't see anything available.

  • ADF41513 spur question

    Hi, ADI PLL expert

    One of my customer plan to use ADF41513 in their new project, but when customer read the datasheet, They got confused about the Spur performance of Figure12 & Figure13.

    1. The test condition of Figure 12 & 13 is 100Mhz PFD & 100Mhz…

  • ADF41513 input impedance


    I would like to ask whether the REFIN and RFIN pins of the ADF41513 PFD are 50inputs or if there are external resistors needed to match the inputs to a 50Ω transmission line.

    Regards, Simon Fuchs

  • Board Size EVAL-ADF41513

    Could you please tell me the size of EVAL-ADF41513?

    My customer is trying to use them in a box.
    I was asked a question about board size.

  • ADF41513 S-Parameters for RFINA/RFINB

    Are there any s-parameters for the ADF41513 RFINA.  Or an equivalent circuit.

    I am trying to do a linear simulation from 10-20GHz of my circuit which includes the ADF41513 connected to a 3dB splitter (EP2K+ as per the ADF41513 EVB) and having the s-parameters…

  • ADF41513 + HMC733 out of band spurs


    I am using ADF41513 with HMC733 as my LO in my system. I noticed that there will be a fixed spurs at 5.7GHz to 6.2GHz with 100MHz spacing (my reference freq) regardless of my LO change from 10GHz to 20GHz.

    1. Is the ADF41513 evaluation…

  • ADF41513 prescaler spurs out of Band

    Hi AD experts,

    I would like to use the ADF41513 with the VCO HMC733 with a PDF of 50MHz. The prescaler will be set up at 8.

    There should have spurs at nF0/8 (with n = 1 to ...) which should leak from RFin. Do you know their level?

  • Questions about the frequency multiplication malfunction of PLL ADF41513

    The SFCW (stepped frequency continous wave) signal of 100M~120MHz was used as the reference signal. The retention time of each freqency step was 10ns, and the step number was 3000. The interger N mode was setted where N=125. So the output frequency (Fo…
