Definition: Power Added Efficiency (PAE) is a measure of how efficiently an RF amplifier converts DC power into RF output power, accounting for the input RF power.
Purpose: PAE is a critical metric for RF amplifier design, especially in wireless communication systems, where high efficiency is needed to reduce power consumption and heat dissipation.
The calculator uses the following formula for PAE:
Where:
Steps:
PAE calculations are essential for:
Examples:
Q: What is Power Added Efficiency (PAE)?
A: PAE measures the efficiency of an RF amplifier by calculating the ratio of added RF power (
Q: Why is PAE important in RF amplifiers?
A: PAE is a key metric for evaluating amplifier efficiency, impacting battery life, thermal management, and overall system performance in RF applications.
Q: How does unit conversion work in the calculator?
A: The calculator converts all power inputs to watts (e.g., 1000 mW = 1 watt, 30 dBm = 1 watt). The PAE is then calculated and displayed as a percentage.
