• ADF5355 Frequency setting issues

    Hello everyone

    I'm using the ADF5355 signal generator board to send signals at a certain frequency and with a certain power level.

    It is programmed using an Arduino Nano with SPI.

    I was able to do this with the code attached to this message (obtained…

  • ADF5355 frequency deviations power supply

    Hello everyone,

    I'm using the ADF5355 board to send signals at a constant frequency in the 1-6GHz range.

    I achieved to do this by programming the registers of the board with Arduino Nano and updating it every time I changed the frequency.

    However,…

  • ADF5355的锁定

    在使用ADF5355这款芯片时,我遇到了一些问题

    频谱仪上可以看到对应的输出频率,但是频率在正负100Hz之内抖动,比较不稳定,所使用的频率源为外置信号源。

    锁定指示中,数字锁定指示为高电平;而模拟锁定指示为低电平。

    请问这样的现象产生的原因是什么呢?

    Even we are facing exactly same issue,  sir can you please guide. We are working with ADF4356 

  • ADF5355 phase noise

    Is there any newer/better device having lower phase noise at around 13 GHz?

  • ADF5355 lock issues

    I am having trouble attaining a lock with the ADF5355 in my current design and would like some suggestions on how to go about trouble shooting.

    1) I have the eval board where I can validate my settings and attain a lock at 6000 MHz.

    2) I have also used…

  • adf5355无法锁定

    当我测试adf5355时发现无法锁定。下面是我测试的一些现象,希望能得到大家的帮助。

    首先,我设置了如下图所示的环路滤波器,带宽为100kHz:

    寄存器的设置如下:

    输入为100M差分信号,实际测试波形如下。它的波形有点失真,不知道这里的影响大不大?

    当muxout引脚设置为R分频输出时,输出为50MHz的波形,这似乎是正确的,但不是规整的方波,这会不会影响锁相环的锁定?

    但当muxout引脚设置为N分频输出时,其输出不再正确,约为37MHz信号。在这种情况下,RFout引脚的输出肯定是不正确的…

  • C/C++ source for ADF5355

    Hello,

    Could you please provide with me the C/C++ source for ADF5355 ?

    Thanks in advance.

  • The adf5355 pll cannot be locked

    When I was testing adf5355,the pll couldn't be locked.Here are some of the phenomena I tested, and I hope to get your help.

    First, I set up the loop filter as shown in the figure below, with a bandwidth of 100kHz:

    The register is set as follows:

  • adf5355有很大的杂散

    请问这个两边的杂散该怎么解决,有可能的来源是哪?
