BFP840FESD

The BFP840FESD is a high performance HBT (Heterojunction Bipolar Transistor) specifically designed for 5-6 GHz WiFi applications. The device is based upon the reliable high volume SiGe:C technology of Infineon. The BFP840FESD provides inherently good input and output power match as well as inherently good noise match at 5-6 GHz. The simultaneous noise and power match without lossy external matching components at the input leads to a low external parts count, to a very good noise figure and to a very high transducer gain in the WiFi application. Integrated protection elements at in- and output make the device robust against ESD and excessive RF input power. The device offers its high performance at low current and voltage and is especially well-suited for portable batterypowered applications in which energy efficiency is a key requirement. The device comes in an easy to use thin flat package with visible leads.
