1. What is an RF amplifier, and what does it do?
RF amplifiers increase the strength of radio frequency signals for various applications, such as broadcasting, communication systems, and signal processing.
-
2. What factors should be considered when selecting an RF amplifier?
Important considerations include gain, noise figure, bandwidth, linearity, efficiency, and the specific application requirements.
-
3. What is the role of linearity in RF amplifiers?
Linearity determines how well an amplifier preserves signal fidelity under varying input power levels, minimizing distortions like harmonics and intermodulation.
-
4. What are Doherty amplifiers, and where are they used?
Doherty amplifiers are specialized power amplifiers that enhance efficiency for signals with high peak-to-average power ratios, often used in modern communication systems.
