  • Difference between ADL5386 and ADL5385

    Hello,

    I am comparing two IQ modulators 5386 and 5385. It was described in the datasheet that ADL5386 has an attenuator that can follow the modulator. My question is: we already can suppress the modulator output signal to almost zero by lowering the…

  • ADL5386 Block Diagram Error at Datasheet

    The log amp detector in ADL5386 can be used to implement an AGC(Automatic Gain Control) loop. A portion of the output signal of the VVA is coupled to the input of the log amp detector. The output current from log detector is compared with the current…

  • RE: Query about ADIsimRF's Modeling

    Noise figure should be set  to the negative of the  insertion loss (e.g. an insertion loss of  -1 corresponds to  a noise figure of +1). P1dB and IP3 can be set to  some very high number like 100.

    ADIsimRF already has a number of passive attenuator models…

  • RE: ADL5386/5387's LO input harmonics

    You do not need a harmonic filter when driving 2XLO based IQ modulators and demodulators such as ADL5385 and ADL5387. More info in the following Circuits from the Lab:

  • RE: Precise phase setting of sinewave RF input signal

    Hello...

    I have a similar application, where I have an sinus RF signal in the range between 150MHz and 450MHz.

    After splitting it, I need to control the relative phase between them with 1 degree accuracy.

    I have been looking into some of your IC, and…

  • 关于两片AD9739的同步问题

    我们在做一个调制器相关项目,用了两片AD9739,分别做I/Q两路输入到调制芯片ADL5386,有两个问题麻烦解答:

    1. 两片AD9739SYNC INOUT实现同步,AD9739-1的OUT作为BUFER的输入,BUFER的输出分别接两片9739的IN,AD9739-2的OUT悬空,这样连接是否正确?这些同步信号是否还需要接到FPGA中去被控制?实现同步的BUFFER1.8V ADCLK846是否可以?
    2. AD9739位70欧姆输出阻抗,而ADL5386位50欧姆输入阻抗,两者之间连接请问如何做阻抗匹配…
  • FAQ: Can AD8346 be operated at frequencies below 800 MHz?

    Question: FAQ: Can AD8346 be operated at frequencies below 800 MHz?

    Answer: For starters, there is only one good reason to try and use the AD8346 at frequencies below its specified 800 MHz minimum. And that reason is the fact that the device has…
