Description

Multi-Channel RF Systems using wide bandwidth signals are common in many applications. Keeping all channels - even distributed ones - well synchronized is a common ask from these types of systems. In reality, RF and baseband synchronization are not perfect though - but how accurate do they need to be for a given application?
Is 1 ps plenty? Is it not enough? Will 10 degree phase offset work fine? Do I need to be any more accurate when using more than a handful of channels? Are there any practical numbers that are guiding us?
Let's find out.
