Infineon BFP842ESDH6327XTSA1 NPN Transistor, 40 mA, 3.25 V, 4-Pin SOT-343

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.
