Product Brief RF transistors 8th generation Best in class performance for WiFi® connectivity The BFx840x product family is a series of discrete Hetero-junction Bipolar Transistors (HBT) addressing dual and fixed frequency Low Noise Amplifier (LNA) solutions for high performance WiFi® connectivity applications. It combines 80 GHz f T silicon-germanium:carbide (SiGe:C) B9HFM process and adopts dedicated device geometry reducing the parasitic capacitance between substrate and transistor degrades high-frequency characteristics and ultimately improved. RF transistor 8th generation allow engineers to increase the RF link budget and Signalto-Noise Ratio (SNR) of their AP routers and mobile stations when wider coverage areas are needed and especially when a higher order modulation scheme is used as in emerging very high throughput wireless specifications such as 256 Quadrature Amplitude Modulation (QAM) in IEEE 802.11ac with more stringent SNR requirements for both the AP and the client.

It is mostly important to achieve with superior performance where losses of the whole RF frontend become critical due to long routing paths for instance in WiFi® architectures with 4x4 MIMO or 8x8 MiMO functions. Infineon 8th generation RF SiGe Bipolar transistors working as LNA deliver the lowest noise figure (NF) of 0.6 dB at 5.5 GHz, highest gain with its high frequency (fT) and superior linearity in comparison to other solutions available in the market. This outstanding performance delivers system sensitivity improvement and interference immunity enhancement and helps engineers to design high-performance WiFi® applications while been price attractive.
