Line 1:
A '''passive electronically scanned array''', as opposed to [[AESA]], is a [[phased array]] which has a '''central''' [[radiofrequency|RF]] source (such as a [[magnetron]], a [[klystron]] or a [[travellingtraveling wave tube]]), sending energy into (usually digitally-controlled) [[phase shift module]]s, which then send energy into the various emitting elements in the front of the [[antenna]]. AESA devices, in contrast, have each of their elements contain its own RF source.
