• HMC862A with no input signal

    Does self-oscillatation occure in the abscence of signal at the input of HMC862A for any division ratios?

    Hi,Could you help to support the gerber file of EV1HMC862ALP3(HMC862A Evaluation Board)?Our customer wish to design the cirucits of HMC862A.

  • RE: Recommended Prescaler

    I got the HMC862A eval board. Did few measurements and saw that the eye height measured at HMC862A is higher than expected. Any comments/feedbacks why I see such results?

  • RE: Divider-by-3 duty cycle

    Hi Chris,

    The HMC862A is more expensive than the HMC434E ($17 versus $5).

    However, it has significantly higher ESD protection.

    As discussed above, I would prefer the cheaper HMC434E with external, on-board, ESD protection.
    I am waiting for inputs from…

  • RE: I am looking for a voltage controlled Oscillator (VCO) in the frequency range 0.5 GHz - 4.5 GHz and to be operated (controlled) using a PWM from an MCU. Any suggestions?

    Hi,

    Unfortunately we don't have any stand alone, varactor tuned oscillators that specifically cover that range. A good solution that minimizes complexity would be the HMC586 (4.0 GHz to 8.0 GHz ) VCO followed by the HMC862A (Div 1/2/4/8) frequency divider…

  • 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…

  • 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…
