**Product Brief** 

## **1 Product Brief** 

The BFP740FESD is a very low noise wideband NPN bipolar RF transistor. The device is based on Infineon’s reliable high volume silicon germanium carbon (SiGe:C) heterojunction bipolar technology. The collector design supports voltages up to _V_ CEO = 4.2 V and currents up to _I_ C = 45 mA. The device is especially suited for mobile applications in which low power consumption is a key requirement. The typical transition frequency is approximately 47 GHz, hence the device offers high power gain at frequencies up to 12 GHz in amplifier applications. The transistor is fitted with internal protection circuits, which enhance the robustness against electrostatic discharge (ESD) and high levels of RF input power. The device is housed in a thin small flat plastic package with visible leads.

## **Notes** 

_1. Gms = IS21 / S12I for k < 1; Gma = IS21 / S12I(k-(k[2] -1)[1/2] ) for k > 1_ 

_2. In order to get the NF min values stated in this chapter the test fixture losses have been subtracted from all measured results._ 

_3. OIP 3 value depends on termination of all intermodulation frequency components. Termination used for this measurement is 50_ Ω _from 0.2 MHz to 12 GHz._

**Simulation Data** 

## **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 BFP740FESD 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 BFP740FESD SPICE GP model reflects the typical DC- and RF-performance within the limitations which are given by the SPICE GP model itself. Besides the DC characteristics all S-parameters in magnitude and phase, as well as noise figure (including optimum source impedance, equivalent noise resistance and flicker noise) and intermodulation have been extracted.
