  • ADL5521: How to operate in 1000MHz?

    Hi:

       I found that the datasheet of the adl5521 only has recommended parts for some frequencies. I want to use ADL5521 at 1000MHz, so how should I choose  suitable resistors and capacitors?

  • ADL5521 OIP3

    Hi,

    I am wondering why you chose 1 MHz for tone spacing when measuring OIP3? Does OIP3 vary with the value of tone spacing? If the tone spacing is reduced, for example delta f = 15 kHz, how does OIP3 change?

    Thank you in advance.

  • ADL5521 OIP3 vs. Output Power

    Hi,

    In figure 14, what is the test condition in this measurement? In specific, what is VPOS and Pin in this case? Do you vary the input power in this measurement?

    Thank you in advance.

  • ADL5521:Impedance matching

    My project needs an LNA in the 1-2GHz range, so I chose the ADL5521.

    When I looked at the datasheet of the ADL5521, I found that there was a problem of impedance matching over a wide frequency range. The typical circuit of datasheet recommends choosing…

  • 关于ADL5521的问题

    你好:

            当我采用datasheet上给的外围元器件(2140MHz)配置ADL5521芯片时,芯片将输入信号衰减了10dB,没有起到放大的作用,但通过电压源可以观察到有电流消耗,并且电源和偏置电阻都正常,另外更换了多次芯片依然是相同的结果,想请问一下这是什么原因导致的?如果检测芯片哪部分或者哪引脚出现问题?谢谢!

  • About ADL5521

    Hello:

        When I use the given peripheral components (2140MHz) on the datasheet to configure the ADL5521 chip, the chip attenuates the input signal about 10dB, does not play the role of amplification, but the current consumption can be observed from…

  • 关于ADL5521的放大问题

    你好:

          我在按照ADL5521芯片手册给出的电路布置的时候(2140MHz频率),外围的电源和偏置电阻都正常,并且能从电压源看到电流消耗,但输出信号衰减了10dB,没有起到放大的作用,替换了多次芯片还是相同的测试结果,请问该如何检测或判断芯片哪部分或哪引脚出现问题,导致无法起到放大效果?谢谢!!
