Morphology
The noun is a straightforward adjective+noun composition: 'superheterodyne' (pertaining to circuits that convert signals to a fixed intermediate frequency) qualifies 'receiver' (a device that picks up signals), so the overall meaning is directly inferable from the parts. Although the term is technical, its structure follows standard English composition patterns, so a learner who knows both constituents can understand the MWE's meaning.
Etymology
Superheterodyne receiver comes from joining super and heterodyne, where heterodyne refers to 'mixing different frequencies'. The receiver's trick is to literally 'mix' the incoming radio wave with a local wave to make a single steady 'middle' tone that is easier to amplify and understand, so the name describes what the device does today.
