• Vtune out-of-spec of HMC733

    Hi, all. We're developing a frequency synthesizer using HMC733 and ADF41513.

    HMC733 datasheet promise around Vtune of 18V for output of 20 GHz. But we observed 21.2 V for output of 20 GHz.

    (we measure Vtune and output freq. as dot in the illustration…

  • ADF41513 + HMC733 out of band spurs

    Hi, 

    I am using ADF41513 with HMC733 as my LO in my system. I noticed that there will be a fixed spurs at 5.7GHz to 6.2GHz with 100MHz spacing (my reference freq) regardless of my LO change from 10GHz to 20GHz.

    See below photo:

    1. Is the ADF41513 evaluation…

  • Converging time to target output frequency of HMC732 and HMC733

    Hi, 

    My customer has measured the converging time to target output frequency with HMC732 and HMC733.

    Their target convergence frequency is Fout +/- 4MHz withing 1us.

    Test results are in below. They made  two constant temperature module with HMC732 and…

  • HMC703 + HMC733 not locking @14,5GHz

    Hello,

    I am using the HMC703 with the VCO HMC733, an active filter and a external prescaler HMC862A (divided by 8). 

    The REF is  100MHz and the PFD = 6,25MHz

    The loopfilter bandwidth is 300kHz and the phase margin 50° (simulation with ADSIMPLL)

    The…

  • Lock time with HMC703 + HMC733

    Hi AD experts,

    I have an issue with the lock time of the PLL HMC703.

    I made a direct measure with a mixer, a RF generator and observe the oscillation at DC with an oscilloscope. The RF generator and the PLL have the same reference. I measure a lock time…
