Morphology

sideband = side + band (semi-transparent) = side + band

The components 'side' + 'band' are visible and literal, but the specific technical sense 'band' = 'range of frequencies' is specialized and may not be known to average learners.

Etymology

Sideband comes from side ('at the side') and band ('a range' or 'strip'). It means the range of radio frequencies that sit like side lanes next to the main radio signal, so they are the signals 'on the side' of the main wave.
