Power added efficiency
From Wikipedia, the free encyclopedia
Power-added efficiency (PAE) is a percentage that rates the efficiency of a power amplifier.
- PAE = 100*{[POUT]RF – [PIN]RF} / [PDC]TOTAL
However, in literature, most power efficiency descriptions refer to a percentage calculated as
- η = 100*[POUT]RF / [PIN]DC
This value is larger than the PAE.
