Thermal Memory Effects on the Linearity of a GaAs PHEMT

open access: yes, 2004
This paper presents a comprehensive treatment of the nonlinear electro-thermal memory effect arising in a GaAs PHEMT. In particular is demonstrated the way with which the pure nonlinear electrical effect and the electro-thermal one combine and in turn determine a dispersive third-order intermodulation.
