Formula:
The Power Added Efficiency (PAE) is calculated using the following formula:
Where:
- PAE is the Power Added Efficiency (in %),
- Pout​ is the output power (in watts, W),
- Pin​ is the input power (in watts, W),
- PDC​ is the DC power supplied to the amplifier (in watts, W).
This formula highlights the importance of maximizing output power while minimizing both input and DC power to achieve higher efficiency.
