Voltage-controlled devices where an electric field determines the conductivity of a channel. 2. Design of Amplifiers
A tuned common-emitter or common-base amplifier at the front end. Its job is to boost the weak signal from the antenna before it hits the mixer. Principle: Neutralization is often required here to prevent oscillation due to collector-base capacitance (Miller effect). Its job is to boost the weak signal

The journey from a single transistor to a complex circuit is one of : Its job is to boost the weak signal
To use a transistor as an amplifier, it must be properly —meaning set to a steady "resting" state so it can handle incoming signals without distortion. Applications II: Amplifiers - Transistors - SparkFun Learn
