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:
“Failure or success seem to have been allotted to men by their stars. But they retain the power of wriggling, of fighting with their star or against it, and in the whole universe the only really interesting movement is this wriggle.”
—E.M. (Edward Morgan)
“Those who can lose shall gain; those who wish for gain shall lose.”
—Chinese proverb.
