BFP842ESD

The BFP842ESD is a high performance HBT (Heterojunction Bipolar Transistor) specifically designed for 2.3 - 3.5 GHz LNA applications. The device is based upon the reliable high volume SiGe:C technology of Infineon. The BFP842ESD provides inherently good input power match as well as inherently good noise match between 2.3 and 3.5 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 high transducer gain in the 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 industry standard package with visible leads.
