The Infineon BFP420 is a low-noise, wideband silicon NPN RF bipolar transistor. It is part of Infineon's fourth-generation RF bipolar transistor family, utilizing a grounded emitter (SIEGET™) structure.
With a transition frequency (fT) of 25 GHz, high gain, and low current characteristics, the BFP420 is well-suited for applications such as oscillators up to 10 GHz. Key electrical specifications include a minimum noise figure (NFmin) of 1.1 dB at 1.8 GHz (2V, 5mA), a high gain (Gms) of 21 dB at 1.8 GHz (2V, 20mA), and an output third-order intercept point (OIP3) of 22 dBm at 1.8 GHz (2V, 20mA).
This device is qualified for industrial applications according to JEDEC JESD47, JESD22, J-STD-020, and AEC-Q101 standards. Potential applications include radio-frequency oscillators and broadband low-noise amplifiers (LNAs) for CATV, DVB-T, DAB/DMB, FM/AM radio, and sub-1 GHz ISM band applications.
The BFP420 is available in a SOT343 surface-mount package. It is an ESD-sensitive device and requires appropriate handling precautions.
