Morphology

bandpass = band + pass (transparent) = band + pass

The sense 'the range of frequencies that pass' is a direct, literal combination of 'band' (range) + 'pass' (to allow through).

Etymology

Bandpass comes from band ('a range or strip') and pass ('let through'). The bandpass is the actual range of frequencies a device allows to pass, so it names which frequencies will get through and which are blocked.
