1. What is the difference between a power amplifier and a low-noise amplifier?
Power amplifiers maximize signal power for transmission, while low-noise amplifiers are used in receivers to amplify weak signals with minimal noise.
-
2. 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.
-
3. How do envelope tracking amplifiers improve efficiency?
Envelope tracking dynamically adjusts the power supply voltage according to the signal's envelope, optimizing energy usage for signals with high peak-to-average ratios.
-
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.
