Super heterodyne receivers.

Superheterodyne Architecture The choice of the IF frequency dictated by: If the IF is set too low, then we require a very high-Q image reject filter, which introduces more loss and therefore higher noise figure in the receiver (not to mention cost). If the IF is set too high, then subsequent stages consume more power (VGA and filters)1. One of the main functions of the RF amplifiers in a super-heterodyne receiver is to.
