SPICE GP Model For the SPICE Gummel Poon (GP) model as well as for the Sparameters (including noise parameters) please refer to our internet website www.infineon.com/rf.models. Please consult our website and download the latest versions before actually starting your design. You find the BFR38F SPICE GP model in the internet in MWO and ADSformat, which you can import into these circuit simulation tools very quickly and conveniently. The model already contains the package parasitics and is ready to use for DC and high frequency simulations. The terminals of the model circuit correspond to the pin configuration of the device. The model parameters have been extracted and verified up to GHz using typical devices. The BFR38F SPICE GP model reflects the typical DC and RFperformance within the limitations which are given by the SPICE GP model itself. Besides the DC characteristics all Sparameters in magnitude and phase, as well as noise figure (including optimum source impedance, equivalent noise resistance and flicker noise) and intermodulation have been extracted. 8 36
