1 Product Brief
The BFP450 is a high linearity wideband NPN bipolar RF transistor. The collector design supports voltages up to
VCEO = 4.5 V and currents up to IC = 170 mA. With its high linearity at currents as low as 50 mA the device supports
energy efficient designs. The typical transition frequency is approximately 24 GHz, hence the device offers high
power gain at frequencies up to 3 GHz in amplifier applications. The device is housed in an easy to use plastic
package with visible leads.

1. AC parameter limits verified by random sampling
2. In order to get the NFmin values stated in this chapter the test fixture losses have been subtracted from all
measured result
3. OIP3 value depends on termination of all intermodulation frequency components. Termination used for this
measurement is 50 Ω from 0.2 MHz to 12 GHz.

6 Simulation Data
For the SPICE Gummel Poon (GP) model as well as for the S-parameters (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 BFP450 SPICE GP model in the internet in MWO- and ADS-format, 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 10 GHz using typical devices. The BFP450 SPICE
GP model reflects the typical DC- and RF-performance within the limitations which are given by the SPICE GP
model itself.
