HMC942LP4E Phase Noise

I do not see any phase noise data or plots in the HMC942LP4E datasheet.

What is the phase noise performance for this divider?

Thanks,
John

  • Hi Chris,
    I actually just sampled the HMC8342 and have been evaluating  It has a very good phase noise performance.

    What I like about the HMC942LP4E is the simpler biasing (single positive supply voltage).

    Would it be possible to have the ADEF apps team measure the phase noise for a 25.6 GHz output signal (12.8 GHz at input) on part number HMC942LP4E?

    Thanks,

    John

  • HI John,

    the additive phase noise measurements are difficult and will take some time.  In terms of being able to give you a quicker response.  Would it be possible to give you an absolute phase noise plot, using a input phase noise source with as good or better phase noise than you are planning to use?    To do this I would need a rough an idea of what your input sources expected phase noise curve looks like.  I imagine you will not want to send this on a public forum.  There is away to direct message me through EngineerZone if this is the case.
