Morphology
The meaning is directly and compositionally derived from 'frequency' (rate of occurrences over time) modified by 'band' (a range or set of values); together they naturally denote a range of frequencies. Although it's a technical term used in radio/engineering, the combination follows a transparent noun + noun modifier pattern common across languages, so a B1 learner who knows both words can infer the intended meaning.
Etymology
The noun frequency band comes from the image of a 'band' as a strip on a scale. People pictured radio frequencies as a long line of waves, and a band is a joined strip of those frequencies next to each other, so frequency band means 'a range of frequencies set aside for one use'.
