• FAQ: AD8354 Thermal Impedance

    Q: What is the definition of θJA for paddle soldered/unsoldered shown in the datasheet?

  • AD8354 bare die

    Hello,

    Do you sell this amplifier as a bare die,  without the package?

     Thank you in advance,

  • AD8354 recommended ground vias

    Hi,

    Are ground vias needed on exposed pad?

    And if not, is it important to place ground vias as near as possible to the exposed pad?

    Indeed the evaluation board doesn't seem to have many ground vias near the exposed pad, which is curious.

    Regards

  • 基于AD9852产生固定频率通过AD8354后不正确

    用AD9852产生固定频率,进入8354前在C37测波形如下:

    在R67端测:

    小频率前端波形很好是正常的,但是通过8354后波形就不对:

    8354已经焊过2个了,应该已经不存在问题了!!!求解答!!原理图:

  • ADL5513 and 1090MHz

    Hi,

    I am trying to receive a 1MHz bandwidth signal with a 1090MHz carrier frequency, since I am not an expert in RF and microwave, i would like to ask you if my current circuit configuration can receive and demodulate the 1090MHz signal using 3 LNAs and…

    谢谢指点,正在使用AD8354做功放的前置放大器。

  • ADI年度贺岁片——使用AD9851和ADL5350做射频电路的时候的问题

    ADI年度贺岁片——使用AD9851和ADL5350做射频电路的时候的问题 by stevenC

            我做过的一个项目中需要用到一些射频器件,其中我使用到的有DDS:AD9851芯片;混频器:ADL5350;RF增益器件:AD8354;自动增益器件:AD8367。大概思路和射频收发器差不错,由DDS产生一个小步进的频率可调的高频信号,用混频器和PLL产生的高频信号混频、滤波后经过放大,驱动功放,在用一个功放期间放大功率后由双工器发送。接收的时候使用到了两次自动增益,然后送入DAC变成数字信号…

  • RE: LNA for LORAN

    AD8353 and AD8354 is specified to operate down to 1 MHz. It can go lower than this. It's just a question of increasing the ac-coupling caps. There is a discussion of this in the apps section of the datasheet along with a plot showing operation down to…
