Radio receivers are a series of progressive signal amplification by a set of cascaded radio frequency (RF) amplifiers. Amplifiers increase the signal level, which means the antenna signal has to be fed to a very sensitive first stage, amplified, and sent to the second stage and so on for further amplification. The first radio receivers built were tuned radio frequency (TRF) receivers, which had RF stages that were all tuned to the receiver frequency. TRF receivers are best suited for receiving only one frequency. For tuning to a wide range of frequencies, TRF receivers may not be practical except in special applications.
