Hi,
I don't know whether this is the right Forum tell me if not.
I'm trying to develop a Phase Detector circuit.
In theory it's pretty simple:
I've got two 400Mhz sine wave signals with different phase offsets.
Then i convert them to a square wave signal by using a simple Op-Amp or Comparator.
Problem 1: I wonder wich Op-Amp I should use for a 400Mhz signal. Or do i need to use some kind of comparator for Frequencies that big?
Problem 2: How do i then perform some kind of XOR Logic?
I thought about adding one Signal in reverse to the other and then cut of any negative current with a diode...
I'm pretty new to this topic, feel free to post any links or Websites which could help.
An Answer would be great!

Cery
