High frequency small signal resonant amplifier

Amplifiers that use components with resonant properties (such as LC resonant circuits ) as loads
are called resonant amplifiers, also known as tuned amplifiers. It is commonly used as high
frequency amplifier and intermediate frequency amplifier in wireless receiving systems .
    The figure shows a high-frequency small-signal resonant amplifier. From a structural point of view, it is very similar to
a common-emitter basic amplifier circuit. The main feature is that it replaces
the collector resistor with an LC parallel resonant circuit. The LC parallel resonant circuit is used. The small signal resonant amplifier
a circuit with frequency selective characteristics.
