Infineon BFP843FH6327XTSA1

The Infineon BFP843FH6327XTSA1 is a low-noise, high-linearity NPN RF transistor optimised for UK RF systems and wireless communication. Housed in a compact PG‑TSFP‑4‑1 surface-mount package, it supports input power up to 20 dBm, operates up to 14 GHz, and delivers a strong OIP3 above 29 dBm. Its high gain (13.5–25 dB across 450 MHz to 10 GHz) and superior noise performance (0.8–1.7 dB) make it ideal for UK RF front-end designs, such as satellite, radar, and telecommunications equipment, where signal clarity and reliability are critical.

Why Sets the Infineon Low-Noise, NPN RF Transistor Apart?

The BFP843FH6327XTSA1 stands out for its unmatched blend of noise performance and linearity. The low noise figure ensures minimal signal degradation during amplification, while the high OIP3 enables excellent intermodulation handling, ideal for crowded UK spectrum applications. Its SiGe technology and robust design deliver consistent gain, even under demanding environmental and frequency conditions.
