• ADL5521

    Hello,

    We were trying to use the s2p file at  http://www.analog.com/en/rfif-components/rfif-amplifiers/adl5521/products/product.html.

    However, the s2p file in not compatible with ADS 2013. Any suggestions?

    Also, we need to get the design/spice model…

  • 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…

  • 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…

  • 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 S-Parameters

    Looking to use the ADL5521 at 1.59GHz. 

    1)  Do the s-parameters on the web include the matching network shown in the datasheet?

    2) Does I need the matching networks or can I  get away without using them?

  • ADL5521 TR (trace) calculations

    Hi,

    In the ADL5521 Datasheet (Rev A, pages 16 and 17), great discussion of the layout and component selection is given, except for TR 1 and 2.

    How do you calculate the value?

    I assume dielectric of the board matters - and wonder how it impacts the…

  • 关于ADL5521问题

    ADI专家,您好:

    我们在产品中采用ADL5521作为第一级信号放大,芯片输入前面为射频天线+三阶带通LC滤波器300M ~1500M,作为射频信号通道板使用。

    但在实际应用过程中,遇到外部强的电磁干扰(如外面高电压试品放电),容易损坏芯片,此时后端表现为无信号输入;

    当把 第一级信号放大 芯片 ADL5521 更换后,电路 板恢复正常。

    类似这样的情况已发生多起,给我们产品生产产生很大问题,请能否出手帮忙指导以解决此问题?

  • 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!

  • ADL5521-ADS simulation for Matching

    Hi,

    I am trying to simulate matching for default setting at 1950MHz, using S-parameter file on the website.

    However, I do not get expected simulation result with the setting you have on the website.

    1. Simulating with the setting on manual.

  • ADL5521 integrated DC blocking capacitors

    Hi,

    ADL5521 data-sheet reports "Integrated DC blocking capacitors" but give no information about max DC voltage that can be applied to pins 2 and 7, could you tell me more?

    And about statics that could be picked up by antenna is there some…
