Simulation Data
For SPICE-model as well as for S-parameters including noise parameters refer
to our internet website: www.infineon.com/rf.models. Please consult our website
and download the latest version before actually starting your design.
The simulation data have been generated and verified up to 12GHz using typical
devices. The BFP405 nonlinear SPICE-model reflects the typical DC- and RF-device
performance with high accuracy.
