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 12 GHz using typical devices. The BFP740 nonlinear SPICE-model reflects the typical DC- and RF-device performance with high accuracy.
