• Wrong response in ADF4360-0

    Hi. I´m trying to do a circuit that generates signals with frequencies between 2.4GHz and 2.725GHz. I´m using ADF4360-0.   Sometimes, the out frequency is right. It has no noise (figure 1).

    But, in other cases, the out frequency is wrong. It has noise…

  • Reflection in output stage of adf4360-0?

    Hello, I'm trying building a synthesizer with an adf4360-0. I have several stages. I have a PCB for the reference oscillator. A PCB for power source. A PCB for filter (it is given because of ADIsimpll) and other PCB for adf4360-0. The oscillator produces…

  • ADF4360-0的使用问题

    由于是第一次使用,很模糊,我想知道这些问题:

    1、ADF4360-0的参考频率是由外界的晶振输入的吗?一般常用什么晶振

    2、ADF4360-0的微控制器,我想用官方推荐的ADUC812,它的程序是通过什么写入的?评估板还是??

    3、我买了4360-0的评估板,评估板具体有哪些作用好处呢?

    本人就是个小白,我知道问题都很低级,希望各位大神和官网技术人员耐心给我解答!先谢谢了

  • Adf4360-0

    First of all thank you very much for your excellent forum, I'm doing a  Design of an Economical Antenna-Gain and Radiation-Pattern Measurement System, for that I dispose of a adf4360 and AD8302 detector, my problem is with adf4360 when checking the…

  • ADF4360-0 pins 9/10 (L1/L2) discrepancy

    Hi,

    I'm working on a design using the ADF4360-0 synthesizer and VCO.

    It's unclear to me what proper termination is for pins 9 and 10 on the IC. The datasheet (Rev. D, table 4) states pins 9 and 10 should be connected to AGND. However, the evaluation…

  • ADF4360-0

    I am a student I have a project am using ADF4360-0 module as frequency synthesizer, I have finished my PCB, now am in the programming stage ,I have some problem regarding programming, First of all I am using VCXO as reference frequency (20MHz) I want…

  • ADF4360-0无法配置,muxout一直为1.1v

    目前我是用fpga编写spi接口去配置ADF4360-0,但一直无反应。我的参考时钟是16Mhz,我有量过ADF4360那端REFIN波形,其有一个直流1.5v左右的偏置,然后交流Vpp在0.6V左右。然后我有将muxout配置成DLD,Dvdd,量测到的波形都是1.1v。现在我不确定是REFIN输入时钟不对,还是spi并没有配置成功。如果没有参考时钟输入,ADF4360可以完成配置吗?如果能,将ADF4360的muxout模式配置成Dvdd模式,该pin会输出3.3V高电平吗?

  • Noise in output stage of adf4360-0

    Hi, I made a new electric diagram for my Synthesizer. The power of out signal  is better. Sometimes, the out frequency is right. It has no noise (figure 1).


    But, in other cases, the out frequency is wrong. It has noise (figure 2).

    What can I do for…

  • ADF4360-0. Reference oscillator connection

    Hello! I intend to use ADF4360-0 in my design. According to it's datasheet you recommend to use FOX801BE which connects to ADF4360 Fref port through T-network with 50Ohm resistor to ground. The question is whether it is appropriate solution cause FOX801BE…

  • ADF4360-0 can not lock

    I used adf4360-0 to synthesize a 2.5GHz clock, but the clock can not lock. the schematic, ADISimPLL simulation file and register configuration values are attached.

    The 3-wire interface is controlled by a FPGA, and the interval between the control latch…
