Is there any major problem in performance running hmc832 evaluation board using 5V?

Thank you for your time,

  • Since the HMC832 is a 3.3V part you can power the eval board from 5V.    The minimum HMC1060 input voltage is the maximum output voltage plus 0.3V.  In theory you only need 3.6V (typical) input.  The only drawback is degraded PSRR through the regulator (see Figure 4) at lower input voltages.
