In a typical radio receiver, there will be, a tuning stage, several IF stages, followed by an audio amplifier. (And a few other ancillary bits we'll ignore here.)
The signal from the aerial could be a microvolt or less, and the voltage required at the audio stage will be a few volts. It is not absolutely essential that any of the amplification take place in the tuning stage. Most of the amplification will take place in the Intermediate Frequency stages, and a little more in the audio stages.
A radio receiver is an electronic device that receives radio wave/signal and convert the information carried by them to a usuable form through speaker. The principal functions of a radio receiver are frequency selection, amplification and detection of signals which are been convert back to its original form through the help of radio speaker.
RF = Radio Frequency
class C
A type of superheterodyne radio using two separate mixers, each producing its own intermediate frequency. The block diagram of such a receiver is like this: RF -> M1 -> IF1 -> M2 -> IF2 -> D -> AF
Radio Frequency is a wireless technology consisting of a transmitter and receiver tuned to the same frequency
A; BUFFER is used for isolation, translation of levels and amplification if needed
RF stands for Radio Frequency, magnetic waves radiate out of the transmitting antenna and are picked up or recovered by the receiving antenna at the receiver.

The mixer in an AM receiver combines the incoming radio frequency (RF) signal with a local oscillator signal to produce an intermediate frequency (IF) signal. This process allows for easier amplification and filtering of the desired audio signal, as the IF is typically at a lower frequency. The mixer effectively translates the high-frequency AM signal down to a more manageable frequency for further processing, enabling clearer audio reception.

Depending on how it is used, it can have different applications. However, RF scanning is where one runs a receiver through a series of radio frequencies (RF), and tries to identify a specific frequency. It can include illegal operations, such as RF scanning wherein a transmitter is used to transmit a scan to interfere with transmitters such as petrol pumps, or scanning to locate cell or wireless telephone transmissions. Or there can be harmless applications such as simply tuning a radio manually.

A tuned rf circuit and a convertor of rf to audio. The crystal radio set is a real basic radio
depends on frequency and power
Yes, a radio transmitter converts an electronic signal (such as audio from a microphone) into radio frequency (RF) waves. These RF waves are then transmitted through antennas as electromagnetic radiation, which can be converted back into sound waves by a receiver like a radio or smartphone.
