transconductance

[¦tranz·kən′dək·təns]
(electronics)
An electron-tube rating, equal to the change in plate current divided by the change in control-grid voltage that causes it, when the plate voltage and all other voltages are maintained constant. Also known as grid-anode transconductance; grid-plate transconductance; mutual conductance. Symbolized Gm ; gm .
A field-effect-transistor rating, equal to the change in drain current divided by the change in gate-to-source voltage that causes it, when the drain voltage and all other voltages are maintained constant. Symbolized gfs .
An amplifier parameter, equal to the change in output current divided by the change in input voltage that causes it. Symbolized gm .

At the maximum power point, the efficiency degradation of the ADPA with respect to the analytical result is due to non-constant transconductance of the class-C biased PPA that starts to saturate before the maximum power level.
To understand this more clearly, we first derive the dispersion relationship of an LHTWFET without considering the transconductance.
