Morphology

radio + frequency

The meaning 'the frequency used for radio waves/communication' is directly derivable from combining 'radio' (relating to radio waves or broadcasting) with 'frequency' (the rate or number of oscillations). This is a straightforward compositional noun phrase following common cross-linguistic patterns, so a B1 learner who knows both words should understand it.

Etymology

The phrase radio frequency joins radio, invisible waves used to send sound or data, and frequency, the idea of 'how often' something happens. So, radio frequency means 'how often' radio waves repeat, and that is why it refers to the invisible waves devices use to send and receive signals.
