A radio receiver always has an rf section which is a tunable circuit connected to the antenna terminals.
Rf signal amplifier circuit diagram.
An rf or if mixer not to be confused with video and audio mixers is an active or passive device that converts a signal from one.
It is there to select the wanted frequency and reject some of the unwanted frequencies.

In other words a power amplifier amplifies the power of the input signal which is why these types of amplifier circuits are used in audio amplifier output stages to drive loudspeakers.
Mixers the ideal mixer an idealized mixer is shown in figure 4 3.

Cb radio frequency amplifier antenna amplifier and more.
The power amplifier works on the basic principle of converting the dc power drawn from the power supply into an ac voltage signal delivered to the load.
The signal from the antenna is applied to the input of the circuit and through c5 is fed to the base of the transistor.
