Product Brief

The BFP843 is a low noise broadband NPN bipolar RF transistor. Its integrated feedback provides a broadband

pre-match to 50 Ω at input and output and improves the stability against parasitic oscillations. These measures

simplify the design of arbitrary LNA application circuits. 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 VCEO = 2.25 V and currents up to IC = 55 mA. The device is especially suited for mobile applications in which

low power consumption is a key requirement. The transistor is fitted with internal protection circuits, which enhance

the robustness against electrostatic discharge (ESD) and against high levels of RF input power. The device is

housed in an easy to use plastic package with visible leads.
