Morphology

downlink = link (transparent) = down + link

A transparent compound of 'down' + 'link' denoting a link that goes downward (from satellite to ground), so the meaning is directly inferable from its parts. [Postprocessing: moved 'down' from base_words to prefix]

Etymology

Downlink comes from the parts down- ('from above to below') and link ('connection'), the same idea you see in download. So a downlink is a connection that brings data down from a satellite or central transmitter to a receiver.
