Re: Simulation models for HMC699 (PLL) with HMC583 (VCO)

Hi Huangzeyan,

Thank you very much for your useful answer.

I have still a couple of questions:

1) Which is the best opamp you may suggest to keep the phase noise as low as possible?

2) I am missing the reason why the phase detector gain is set to 2 V/rad in the main window. This is my reasoning:

a) Each port of the phase detector balanced output (UN and UD) swings 2 Vpp for 2pi radians. The balanced signal should thus swing 4 Vpp for 2pi radians, thus approx. 0,64 V/rad. Where am I wrong?

Thanks again and best regards.
