• HMC659-Die S-parameters

    Hello,

    Please share S-parameters of HMC659-Die.
    S-parameters of HMC659-Die cannot be found in ADI web site.

    Is using HMC659-Die with Vdd=5V Idd=100mA possible (recommended)?

  • HMC659-Die applying RF power while power supply and biasing are off

    Hello,

    Is there any problem applying RF power to IN (Pad No.1) while power supply and biasing (Vdd, Vgg1 and Vgg2) are off?

    Best Regards,

    On the use of eval-hmc659:
    1. How to provide power supply vgg1 and vgg2, and how many are they (vgg2 = 3V, vgg1 = - 2 ~ 0V in Datasheet)?
    2. How to connect rfin and rfout? Can the input signal rfin be sine wave and pulse with DC bias (the frequency range…

    您好,感谢对ADI产品的关注。

    HMC659可以直接使用HMC980进行供电https://www.analog.com/media/en/technical-documentation/data-sheets/hmc980.pdf,文档给出了相应的供电电路。输入一般是要加电容做AC耦合的,输入频率范围在接近直流时,性能不能保证,详见数据手册的测试结果。

  • HMC659 biasing sequence

    Hello,

    In case that Vgg1 is pre-adjusted and fixed by register divider, is following sequence no problem?

    The biasing sequence:
    A) Set Vgg1 (Idq adjusted voltage, fixed to somewhere between -2V and 0V)
    B) Set Vdd to +8V
    C) Set Vgg2 to +3V
    Timing: A)<B)…

  • DC power supply for HMC659 evaluation board

    Hi,

    We have bought a HMC659 evaluation board and according to the datasheet, a +8 V DC should be applied to Vdd. However, on the evaluation board there is no Vdd, but a Vgg1 and Vgg2 and there is no clear information on how should the DC power supplies…

  • HMC659: Is RF output waveform inverted to RF input?

    Hello,

    Is RF output waveform inverted to RF input?

    Why asking this question is that:
    High speed TX unit and RX unit is developed separately where high speed data is amplified by HMC659. HMC659 is located at boundary of TX and RX unit on TX side. So…

  • 2HD, 3HD data of HMC441-Die and HMC462-Die

    Hi, 

    Could you share the 2nd and the 3rd harmonic distortion data?

    If there is no data of these products, something of the same product series is also fine.

    Regards,
