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:
“Caring for children is a dance between setting appropriate limits as caretakers and avoiding unnecessary power struggles that result in unhappiness.”
—Charlotte Davis Kasl (20th century)
“Competition is. In every business, no matter how small or how large, someone is just around the corner forever trying to steal your ideas and build his success out of your imagination, struggling after that which you have toiled endless years to secure, striving to outdo you in each and every way. If such a competitor would work as hard to originate as he does to copy, he would much more quickly gain success.”
—Alice Foote MacDougall (1867–1945)
