• ADF5902: How is the TX chirp range ?

    Hi Teams

      We plan to use ADF5902+ADF5904 to develop 24G FMCW, There are two question need to confirm. thanks 

      1) Would you pls. check the chirp range of ADF5902 ?  Can it support TX slope above 4 mHz/uS ? 

    2) Can support 2pcs ADF5902 and 4 pcs ADF5904 in…

  • ADF5902 TX_DATA as Ramp Clock Problems

    Hello,

    I want to generate a FMCW Ramp from 24.0 to 24.25 GHz. I want to trigger the Ramp steps with the TX_DATA pin from a STM uC. The Step word is set to 8192 and the Dev-word to 5120.  My Ref_IN is ac coupled with a 100MHz oscillator. For normal countinius…

  • ADF5902: Peak Transmit Power

    Hi,

    We are currently developing a product with the ADF5902 in 24GHz ISM band and want to verify the peak transmit power based on the Datasheet/our measurements. From what we measured on our spectrum analyzer we got a max power of 8.5dBm while the datasheet…

  • Frequency Shift Keying (FSK) for ADF5902

    Hello,

    Does the ADF5902 have the ability to due frequency key shifting (FSK)? I originally was considering the ADF5901/ADF4159 however shifted gears to this part as it was cheaper and the project is cost-driven. I know the ADF4159 had the ability to do…

  • ADF5902 phase difference between TXs

    Good day,

              We'd like to use ADF5902 in MIMO radar, do you have any test data about  phase difference between the two TXs, i fail to find it among web documents.

  • ADF5902 readback sequence - temperature sensor

    Hi, in the adf5902 datasheet pag 33 says this:

    but I dont understand why do you need the steps 5 and 6, are they necessary?, or could I program the adf5902 until the step 3 and have the ADC out signal always in DOUT?

    Thanks

  • ADF5902 CPOL and CPHA

    Hi, I am designing the SPI master to load the registers for config the ADF5902, please help me to answer this questions:

    1.- according to the datasheet (fig2) and the timing diagram of the SPI protocol I understand that the correct values for the ADF5902…

  • ADF5902 Wandering noise

    HI!

    ALL,We use adf5902 and adf5904 in our design ,During the test,

    1.we found that the rf output tx of adf5902 has Wandering noise,The following video shows

    My question 

  • ADF5902 register 7 - master reset

    Hi, the step 1 in the intialization sequence says to write 0x02000007 in R7, this means that the MSB of this register is 00000010

    but the adf5902 datasheet pag 23 says that DB24 is reserved and should be 1 but in the initialization sequence they are…

  • RE: ADF5902 Can not configure R7 Register

    Hi, did you load all the initialization sequence and after that you used the readback register?, I am trying to read any register but always gives me 0, what steps did you follow?, thanks
