  • RE: About the FSK of ADF4159

    Hello,

    About the ADF4159,

    Can we set the frequency deviation to be different from step to step?

    The figure below is an example.

    In the ADF4159 datasheet P15 Figure15, the frequency deviation looks the same step by step.

  • RE: the parameter of the adf4159 and adf5901?

    ADF5901 24GHz with AUX set to DIV4 and 250MHZ BW

    ADF4159 is (24GHz/4) 6GHz and sweep of (250MHz/4)62.5MHz

    I suggest use the DIV2 option when using the ADF4159.

  • Query about Phase Difference of ADF4159 When Sweeping or Ramping

    Hi, there

    I have a query about ADF4159. When ADF4159 works in ramping or sweeping mode, is the output phase continuous?

    Thanks advance for your kindly help!

  • RE: ADF4159 PSK

    Hi!  Please help me to configure ADF4159 in PSK mode.

    VCO is ADF4351. Frequency 1600 MHz. TxData clocked 500 kHz, but on pin CP ADF4159 const level.

  • MSK Modulation

    Hi,

    I want to create a transmitter with 900MHz frequency and "MSK Modulation",i used ADF4159 to create waveform,is there a chip like "ADF4159" to create msk modulation? thanks.

  • RE: CLK1 and CLK2 values for a ramp in ADF4158

    The limitation that CLK1 and CLK2 cannot be equal 1 at the same time is for the ADF4159. The ADF4159 and ADF4158 share the same software. You can ignore the software warning when using the ADF4158.
