Q.

How does the AD8302 gain/phase detector respond when it is driven by signals such as a modulated carrier whose phase is changing continuously?

 

-----------------------------------------------------------------------------------

A.

The AD8302 does not need to be driven by two fixed-phase signals to produce a valid output. The device AD8302 works just as well when driven by modulated carriers whose amplitude and phase are continuously changing.
