• ADF4158 simulation

    Hi,

    I`m wondering if is available an LTspice model of the ADF4158 to simulate the sawtooth waveform generator. 

    Moreover, I`m asking if there are High-Reliability components that are able to generate a sawtooth waveform (two output with one delayed) or…

  • RE: ADF4158 Integer mode setting with EVB software

    Hi,

    I have made some progress. I tested ADF4159 and I was able to remove PFD/2^26 offset when using the datasheet procedure to disable SDM. See attached plots. (Note the PFD freq was 100MHz with ADF4159 measurement, so offset is 1.49Hz). There is another…

    ADF4158的RFin可以工作在双端输入模式吗?手册和评估板都是给的单端输入,另一端通过电容耦合到底,不是很明白,这样会不会有风险呢

    If only I had found out this earlier. I wasted much time on writing the code a month ago.

    Dear Sir
       I want to generate delay between ramps for clipped triangular mode signal use ADF4158, but I can not find which is register? 

                           thank you !

    HI,

    Im testing An ADF4158 Evaluation Board

    While I testing the frequency 5.8 GHz (default) then a frequency of 5.7 GHz appears on the analyzer spectrum

    Someone has encountered a problem or knows how to solve it??

  • adf4158 muxout

    I'm using ADF4158 in my FMCW radar and tring to generate a continous sawtooth waveform.And I am sure the SPI writing timing meets the requirements in the datasheet.But the time may be more longer than the datasheet given out.For example, the LE set up…

    Hello.

    I need Chirp generator, so look into ADF4158.

    Have some questions.

    1. What is the upper and lower limit for ramp duration ? (I want to control ramp duration)

    2. How fast can I sweep frequency? (=delta F/delta T)

    3. Can I get fre-time characteristic…

  • ADF4158 MUXOUT

    Hi all,

    It seems that two types of DIVIDER output can be selected for the MUXOUT of the ADF4158.

    R or N-DIVIDER OUTPUT, R or N DIVIDER/2
    R-DIVIDER OUTPUT
    N-DIVIDER OUTPUT
    R-DIVIDER/2
    N-DIVIDER/2

    question 1
    Is the understanding of the following signals correct…

  • ADF4158

    Hello, I have also done a frequency synthesizer, the core chip is ADF4158, and the control part is also used CY7C68013A, want to use the evaluation software to debug, how to deal with? What drivers are you downloading? Does the program need to be modified…
