High gain and low noise Infineon BFP840FESDH6327XTSA1 transistor designed for 5 GHz band industrial
Product Overview
The BFP840FESD is a discrete RF heterojunction bipolar transistor (HBT) with integrated ESD protection, specifically designed for 5 GHz band applications. It offers a unique combination of high RF performance and robustness, featuring a maximum RF input power of 20 dBm and 1.5 kV HBM ESD hardness. With a high transition frequency (fT = 85 GHz), it delivers class-leading noise performance (NFmin = 0.75 dB at 5.5 GHz) and high gain (Gms = 23 dB at 5.5 GHz). This transistor is suitable for low voltage applications such as VCC = 1.2 V and 1.8 V, and is qualified for industrial applications.
