• RE: spurs out in ADRF6720

    Hello,

    It looks there are 60MHz +/- N* 8KHz spurs on DAC output and Frf +/- N*16KHz spurs on ADRF6720 output spectrum. It looks spurs on ADRF6720 output are related to spur on input(DAC output) Can you check Baseband inputs to ADR6720 and LO output of…

  • RE: Can AD9152 be connected to ADL5375?

    Hi

    There are two versions of ADRF6720. One is ADRF6720 that asks 0.5V common mode voltage and the other one is ADRF6720-27 for 2.7V common mode voltage. So ADRF6720-27 matches to AD9152.  Please refer to below figure 45 for two combinations of DAC and Modulator…

  • RE: ADRF6720-27 RFoutput problem。

    Hello Oh,

    How does the baseband inputs of ADRF6720-27 interface to? If it is DAC like AD9152/AD9154, ADRF6720-27 can interface to AD9152/54 directly in DC coupling like Figure 45 in ADRF6720-27 datasheet. If you are in AC coupling application, you need…

  • RE: DAC AD9115 with ADRF6720-27

    It is good to hear ADRF6720 works.

    FYI, If you consider ADRF6720-27, it can interface to AD9152/54 directly without a level shifter.

    Thanks

    Hello, we are using ADRF6720 in a custom device, no EVALZ.

    I cannot get the right RF frequency at output. I have 26Mhz ref input. I want 2500Mhz rf output.

    I only change ref in divider and integer-fractional divider value, all other registers remain…

  • adrf6720

    We are using a 10 MHz frequency reference from a GPS on the ADRF6720.  It looks like our output frequency randomly shifts by about +/-1.25 Hz around the desired frequency.  Is this normal, and is there some setting that could limit these frequency changes…

  • RE: Problem with ADRF6720 Eval Board

    Hello,

    I have couple questions regarding to ADRF6720 Eval Board.

    1. Is it possible to control two ADRF6720 Eval Boards with one GUI & one laptop?

    2. Is it possible to control/talk to ADRF6720 Eval Boards through API by using Matlab?

    Thanks in…

  • ADRF6720 LO OUTPUT single ended mode

    Hello,

    I would like to use ADRF6720 LO output to drive ADL5380 LO input.

    Can I use ADRF6720 LO output pin in single ended mode?

    Let s say ADRF6720 LO output pin + connected to the ADL and ADRF6720 LO output pin - to the ground via a capacitor.

    Thanks for…

  • AD-FMCDAQ2-EBZ to EVAL-ADRF6720

    Can I directly connect the AD-FMCDAQ2 to the ADRF6720-EVALZ?  Or do I need to either add baluns between the two boards, or change some of the components on the ADRF6720-EVALZ board?
