What Is a Broadband Amplifier?
A broadband amplifier, or broadband amp, is designed to amplify signals across a wide range of frequency bands. It achieves this through a circuitry that includes multiple transistors, each amplifying signals within specific frequency ranges. By integrating these transistors, the amplifier can operate over a broad spectrum of frequencies.
There are two main types of broadband amplifiers: resonant and wideband. Resonant amplifiers use transistors coupled with resonant circuits to focus on specific frequency bands, whereas wideband amplifiers employ a combination of transistors to achieve amplification across a wider array of frequencies. They are prized for their versatility, potential for miniaturization, and energy efficiency, making them ideal for a variety of applications where broad frequency coverage is required.
