Infineon BFP640H6327XTSA1 NPN RF Bipolar Transistor, 50 mA, 4.1 V SOT-343

The Infineon silicon germanium carbon (SiGe:C) NPN heterojunction wideband bipolar RF transistor (HBT) in a plastic dual emitter standard package with visible leads. The device is fitted with internal protection circuits, which enhance robustness against ESD and high RF input power strongly. The device combines robustness with very high RF gain and lowest noise figure at low operation current for use in a wide range of wireless applications. The BFP640ESD is especially well-suited for portable battery-powered applications in which reduced power consumption is a key requirement. Device design supports collector voltages up to 4.1 V.

Robust high performance low noise amplifier based on Infineon's reliable
2 kV ESD robustness (HBM) due to integrated protection circuits
High maximum RF input power of 21 dBm
