Superheterodyne Receiver

A type of receiver that uses a mixer to convert the RF echo to an IF signal for amplification.

The most widely used radio receiver in which the incoming signal is fed into a mixer and mixed with a signal from a local oscillator. The output produces an intermediate frequency that is amplified through an IF strip, detected by a diode and amplified in an audio amplifier.
