Its 21 dB gain at a typical bias point gives one stage enough headroom for most receiver front-ends before the mixer. The 1.1 dB noise figure at 1.8 GHz keeps the system noise floor low — useful for cellular infrastructure, satellite downconverters, and test equipment front-ends. Collector-emitter breakdown is 5 V, so keep the supply rail under that; this is a low-voltage signal transistor, not a power device. Maximum collector current is 35 mA, and total power dissipation is 160 mW — sized for small-signal duty, not final-stage amplification.","metaTitle":"Infineon BFP420E6327 RF Transistor, NPN, 25 GHz, 21 dB Gain","metaDescription":"Infineon BFP420E6327 NPN RF transistor. 25 GHz transition frequency, 21 dB gain, 1.1 dB noise figure at 1.8 GHz.
