Definition

radio amplifier (noun): An electronic device that increases the power, voltage, or current of a radio-frequency signal, typically used to boost the strength of radio waves for transmission or reception.

Usage Examples
  • (The device made the weak radio waves stronger.)
  • (The device is essential for extending the range of radio signals.)
  • (The device was tuned to enhance clarity.)
Advanced Usage
  • "Radio frequency (RF) amplifier": A specific type of radio amplifier designed for high-frequency signals.
    • The RF radio amplifier is critical in satellite communications. (It boosts signals at very high frequencies.)
  • "Linear radio amplifier": An amplifier that produces an output signal proportional to the input, minimizing distortion.
    • A linear radio amplifier ensures clear audio reproduction in amateur radio setups. (It maintains signal fidelity.)
Variants and Related Words
  • Amplifier (noun): A general device that increases the strength of any electrical signal.
    • The audio amplifier boosted the sound from the speakers. (A device for sound signals.)
  • Radio (noun): The technology of transmitting and receiving electromagnetic waves for communication.
    • He turned on the radio to listen to the news. (The medium that uses radio signals.)
  • Amplify (verb): To increase the strength or magnitude of something.
    • The circuit amplifies the incoming radio signal. (It makes the signal stronger.)
