Its 47 GHz transition frequency and noise figure that runs from 0.5 dB at 150 MHz to 1.45 dB at 10 GHz make it a natural first-stage LNA in base-station receivers, satellite downconverters, and microwave backhaul radios. The 4.7 V collector-emitter breakdown and 45 mA max collector current keep the bias low and the noise match tight — this is not a general-purpose switching transistor. ## Package and mounting Gain spans 9 dB to 31 dB. The 4-TSFP package is a flat-lead SMD, 4-pin. ## Lifecycle and sourcing — active, no LTB watch The BFP740FESDH6327XTSA1 carries an active lifecycle status and is ROHS3 compliant. For a BOM freeze or a new design, this transistor does not introduce obsolescence risk.","metaTitle":"Infineon BFP740FESDH6327XTSA1 NPN RF Transistor, 47 GHz fT","metaDescription":"Infineon BFP740FESDH6327XTSA1 NPN RF transistor, 47 GHz transition frequency, gain 9–31 dB, noise figure 0.5–1.45 dB.
