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 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.
-
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 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.
