Transducer Power Gain
The transducer power gain of a two-port network, GT, is defined as:
where
- Pload is the average power delivered to the load
- Psource,max is the maximum available average power at the source
In terms of y-parameters this definition can be used to derive:
where
- YL is the load admittance
- YS is the source admittance
This result can be generalized to z, h, g and y-parameters as:
where
- kxx is a z, h, g or y-parameter
- ML is the load value in the corresponding parameter set
- MS is the source value in the corresponding parameter set
Psource,max may only be obtained from the source when the load impedance connected to it (i.e. the equivalent input impedance of the two-port network) is the complex conjugate of the source impedance, a consequence of the maximum power theorem.

Famous quotes containing the words power and/or gain:
“All goes to show that the soul in man is not an organ, but animates and exercises all the organs; is not a function, like the power of memory, of calculation, of comparison, but uses these as hands and feet; is not a faculty, but a light, is not the intellect or the will, but the master of the intellect and the will; is the background of our being, in which they lie,—an immensity not possessed and that cannot be possessed.”
—Ralph Waldo Emerson (1803–1882)
“Give way to your opponent; thus will you gain the crown of victory.”
—Ovid (Publius Ovidius Naso)
