En électronique, un récepteur hétérodyne est un récepteur conçu sur le principe du mélange de fréquences, ou hétérodynage, pour convertir le signal reçu en une fréquence intermédiaire plus basse qu'il est plus facile d'utiliser que la fréquence reçue en direct. Super Heterodyne Receiver 1. Recall that a superhet receiver operates by converting the desired incoming RF carrier frequency down to the IF or intermediate frequency, where most of the amplification is provided and receiver bandwidth is defined. RECEIVER GROUP; ANTENNA. An obvious advantage is that by reducing to lower frequency, lower frequency components can be used, and in general, cost is proportional to frequency. This enables signals to be translated from one frequency to another. Madadi, Iman, MassoudTohidian, and Robert Bogdan Staszewski. Presentation Summary : SUPERHETERODYNE RECEIVER.

The diagram below shows the basic elements of a single conversion superhet receiver. Signals enter the receiver from the antenna and are applied to the RF amplifier where they are tuned to remove the image signal and also reduce the general level of unwanted signals on other frequencies that are not required. The superheterodyne receiver is still the most popular microwave receiver, and it was invented during and directly after the Great War and patented in 1918.
