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 are the latest advancements in RF amplifier technology?
Innovations include gallium nitride (GaN) technology for higher power density and efficiency, and digital predistortion techniques for improved linearity.
-
3. 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.
-
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.
