1.1 Characteristic values

We remind you of the definitions of the main quantities needed to understand the following paragraphs.

1.1.1 Electrical efficiency and PAE

The collector efficiency η (electrical) of an amplifier stage is by definition the ratio of the RF power delivered to the load to the power consumed by the DC power supply:

η = P_{s} / P_{a}
