It targets low-noise amplifier front-ends, driver stages, and oscillator buffer circuits from 900 MHz through 1.8 GHz, where the noise figure sits at 0.9 dB to 1.2 dB across that band. Collector current is rated to 20 mA maximum, collector-emitter breakdown at 12 V, and maximum power dissipation at 175 mW. The dual-transistor configuration saves board space and matches pairs for gain symmetry in differential or cascode layouts. ## Lifecycle and compliance No end-of-life notice or last-time-buy schedule applies. The part is available through independent distribution and quoted to order against an RFQ.","metaTitle":"Infineon BFS481H6327XTSA1 RF Transistor, 2 NPN Dual, 8 GHz","metaDescription":"Infineon BFS481H6327XTSA1 RF transistor: dual NPN, 8 GHz fT, 20dB gain, 0.9–1.2dB NF.
