• gerber file of EV1HMC862ALP3

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

  • RE: HMC862A with no input signal

    The circuit will not oscillate in a clean environment. 

     We did not design in a hysteresis on the input. This means if there is a large amount of system noise that is presented to the HMC862A inputs (when a signal is not connected to the input), its possible…

  • Spice model and S-parameter for HMC862A and HMC361G8

    Hi

    The customer hopes Spice model and S-parameter for HMC862A and HMC361G8. Could you please let me know how to get them ?

    Regards,

  • 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…
