1. 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.
-
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 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.
