• working with ADRF6820-EVALZ + ADRF6820 Customer Evaluation Software.

    Hi, RF and Microwave Team!

    Could you please help us with question about ADRF6820-EVALZ?

    Now we are working with ADRF6820-EVALZ + ADRF6820 Customer Evaluation Software.

    And there are some problems:

    1. According to technical documentation ADRF6820 has…

  • RE: Reg ADRF6820 IC

    Hi,

    Unfortunately, many of our Demods with Integrated VCO/PLL’s (like the ADRF6820) are on the track to EOL (aka NRND status) due to a process EOL at one of our foundries. The only ones that don’t fall into that category are shown below and it’s only…

  • ADRF6820

    Hi all,

    is there an example how to program the ADRF6820 for a given frequency. I tried to do but the PLL does not lock.

    When understood correct,i only beed to change the LO frequency , steprate and reference freq. in the Eval-GUI, but

    as sayed PLL…

  • ADRF6820 enable time

    Hi,

    which is the demodulator enable time using the external enable signal?

    I'm assuming the register 0x10 is configured so that to exclusively control the demodulator block and keeping the PLL ON?

    Thanks

  • about ADRF6820

    Hi,

    1. What is the function of  "PWRDWN" switch on evaluation board?? No matter "PWRDWN" is pull high or pull low, ADRF6820 still working.

    2. When using internal LO,

        RFIN : 1900MHz, 0dBm, CW tone

        REFIN : 153.6MHz, 0dBm, CW tone

        LO set…

    ADRF6820初始化后锁不住,不知道是不是初始化时寄存器的顺序有要求,不知道谁用过这个片子的。

  • ADRF6820 and ADRF6720

    Hello,

    I'm testing a system made by a chain of ADRF6720 and ADRF6820 with a modulator with I/Q source (TX) and a demodulator with I/Q receiver, Here the scheme

  • ADRF6820 MUX Pin?

    With respect to the ADRF6820, can someone provide a definition of the MUX pin functions?  Some are obvious, but others are not.  How about an updated datasheet?

    Thanks
