A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency. It was invented by French radio engineer and radio manufacturer Lucien Lévy.

A superheterodyne receiver works by frequency converting ("heterodyning"—the "super" part is 1920s vintage advertising hype) the RF signal. This occurs by nonlinearly mixing the incoming RF signal with a local oscillator (LO) signal.
Macrohenrydyne Most Powerful One Transistor Radio
A superheterodyne receiver uses signal mixing to convert the input radio signal into a steady intermediate frequency (IF) that can be worked with more easily than the original radio signal that has a different frequency, depending on the broadcasting station.
Superheterodyne receiver Wiki Everipedia
It is a type of receiver which mixes the received signal frequency with the frequency of the signal generated by a local oscillator. The output of mixer provides a lower fixed frequency also known as intermediate frequency.

The simple, three-IC superheterodyne radio in Figure 1 can receive stations in the 4.5- to 10-MHz range from around the world with only a 10-ft antenna. A superheterodyne radio works by mixing the incoming RF signal with a local-oscillator (LO) signal to produce an IF. We don't need to spell it out.
