The 0.5 dB noise figure at 1.8 GHz and 0.85 dB at 6 GHz define the noise floor contribution in a cascaded receiver. Paired with 27 dB gain, this transistor can lift a weak signal above the noise of the following mixer or ADC driver without adding significant noise of its own. The 30 mA collector current and 160 mW power dissipation budget mean the bias point can be set for a compromise between linearity and current draw — useful in battery-powered or thermally constrained enclosures. ## Package and mounting — SOT-343 footprint The PG-SOT343-4-2 package is a four-lead surface-mount footprint with a collector pad that also serves as the thermal slug. The 150 °C junction temperature rating gives headroom for high-gain stages in compact RF modules.","metaTitle":"BFP740H6327XTSA1 RF NPN Transistor, 42 GHz","metaDescription":"Infineon BFP740H6327XTSA1 NPN RF transistor. 42 GHz fT, 27 dB gain, 0.5 dB noise figure at 1.8 GHz.
