1. What are the main types of RF amplifiers?
Common types include low-noise amplifiers (LNAs), power amplifiers, variable gain amplifiers (VGAs), and high-linearity amplifiers, each designed for specific tasks like minimizing noise, maximizing power, or ensuring signal clarity.
-
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 is the purpose of a variable gain amplifier (VGA)?
VGAs allow dynamic adjustment of gain to accommodate signal variations, commonly used in systems requiring automatic gain control or signal stabilization.
