C for the WCu and Cu-laminate RF-PA components, respectively. These values
reflect factors involved in the present design of the RF-PAs, its constellation of the thermal resistances
and usual mounting practices.

SIMULATIONS
A full 3D, half symmetry, model was developed and implemented in the software code Ansys80. A
parametric FE-model for the RF-PA component was constructed in the ANSYS APDL language. The FE-
simulations were carried by using a sequential coupled-field analysis.
