For examples and ready to use parameters

please contact your local Infineon Technologies

distributor or sales office to obtain a Infineon

Technologies CD-ROM or see Internet:

Valid up to 6GHz

For non-linear simulation:

• Use transistor chip parameters in Berkeley SPICE 2G.6 syntax for all simulators.

• Simulation of the package is not necessary for frequencies < 100MHz.

For higher frequencies please add the wiring of the package equivalent circuit

around the non-linear transistor.
