The BFR79, manufactured by Semelab, is a silicon NPN bipolar junction transistor (BJT) primarily designed for high-frequency applications in the UHF and microwave bands. Fabricated using an advanced process technology, the BFR79 exhibits a high transition frequency (fT) typically exceeding 5 GHz, enabling its use in oscillators, amplifiers, and mixers operating at these frequencies. Its low noise figure, typically around 2.5 dB at 1 GHz, makes it suitable for sensitive receiver front-end applications. The device features a low collector-base capacitance (Cob) contributing to its high-frequency performance and minimizing feedback effects. The BFR79 is typically supplied in a small-signal surface-mount package, such as SOT-23 or similar, facilitating high-density circuit board assembly. It is characterized by a collector-emitter breakdown voltage (Vceo) suitable for low-voltage operation and a maximum collector current (Ic) rating that must be observed to prevent device failure.
