In ADA8282 I have found something about phase matching but it not clearly defined what it is.
Now I wanna now, can I add 4ch of it's output with single differential summer OpAmp? since it match signals, then there will be no destructive summing caused by antenna reception phase difference?
What is meaning of datasheet quote:
matching the ac performance
between channels improves the distance and angle resolution of a detected object, particularly the phase matching in the band of interest for the application. The ADA8282 layout and design are optimized to increase phase matching. The ADA8282 also has
sufficient bandwidth to minimize any channel to channel phase
variation for up to 5 MHz input signals.
