HMC439 use as frequency Comaprison

Hello,

Yes you can try using the HMC439 like this, but it was never intended to be used in this way. It was only intended to be used in PLL applications. There may be some hysteresis when using the HMC439 like this. Using a mixer may be a better option

Thank you Aandrews.

The output of mixer will be an IF frequency and i want a DC Voltage so i think mixer cannot be used.

One more thing i want to ask is Lets say my Reference is 100 MHz and Input Frequency varies from 130 to 140 MHz. Will i be able to detect error voltage change as input frequency changes with 1MHz step
