Superheterodyne receiver: History, Principle of operation & Overview

The superheterodyne receiver, commonly called the superhet, is a radio receiver that uses heterodyning to convert incoming radio-frequency (RF) signals to a fixed intermediate frequency (IF). The signal is then amplified and filtered at that fixed frequency. This arrangement separates tuning from most of the gain and filtering: the RF circuits make an…
