Morphology
radio-frequency + spectrum
The phrase is directly compositional: 'spectrum' means a range and 'radio-frequency' (radio + frequency) specifies the portion of the electromagnetic range used for radio/wireless services. This modifier+noun structure is transparent and cross-linguistically common, so a B1 learner who knows the constituent words can reliably infer the meaning.
Etymology
The term radio-frequency spectrum comes from the old idea of spectrum, which first meant the range of colours in a rainbow. People started to use spectrum for any 'range', and added radio and frequency to show what kind of range. That's why radio-frequency spectrum means 'the range of radio signals used for wireless communication'.
