• RE: HMC703+HMC632

    您好,请问您的这个问题解决了吗?我也遇到了相同的问题,怎么样才能使仿真锁定呢?

  • HMC703+HMC632

    i use adisimpll 4.01

    pfd100MHZ      freq out:15.4~15.6G  frac mode

    loop bandwidth :100khz   phase margin:60deg

    but it can't lock 

    did not lock to within1.0kHz

    did not lock to within 10Hz

  • RE: ADF4159

    Hi,

    The divide by 2 o/p from the HMC632 can be used to feedback the RF signal to the ADF4159, however the  HMC632 VCO is limited to 15.65GHz, regards Brigid.

    Hello

    I would like a feedback from experts about my design 

    I'm trying to generate fmcw waveforms (sawtooth, triangle) sweeping from 28.5 GHz to 31 GHz

    1. Does the frequency multiplier worsen phase noise? I have done all…

  • RE: HMC703

    ADISimPLL indicates a lock condition after about 160us but to see a decrease in phase error you must increase the simulation time to 350us.   This is similar to your other post at HMC703+HMC632  .

  • RE: HMC735 biasing question

    This evaluation board is used across multiple models, some of which have an additional amplifier to boost the RFOUT /2 power (e.g. HMC632), this is not the case for the HMC735 however. The DS clearly has an error as it seems to indicate that  bias is required…

  • Equivalent Hours of HMC764LP6CE & HMC783LP6CE

    Dir Sir,

    I would like to know the equivalent hours of HMC764LP6CE & HMC783LP6CE. I cnn't find the information in the attached Reliability Report. How can I calculate that value?

    Best regards,

    Akira
