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. How is an RF amplifier's gain measured?
Gain is typically expressed in decibels (dB) and represents the ratio of output to input signal strength. It is a key performance metric for RF amplifiers.
-
3. What factors should be considered when selecting an RF amplifier?
Important considerations include gain, noise figure, bandwidth, linearity, efficiency, and the specific application requirements.
-
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.
