Shenzhen Mingjiada Electronics supplies genuine, in-stock Infineon BF776 high-performance NPN bipolar RF transistors: the ideal choice for low-noise amplifier designs
BF776 Product Overview
The BF776 is a high-performance NPN bipolar RF transistor (SiGe HBT) launched by Infineon Technologies, specifically designed for high-performance low-noise amplifier (LNA) applications. The device is housed in a standard SOT-343 package with visible leads, facilitating soldering and inspection, whilst complying with RoHS lead-free environmental requirements.
The key advantage of the BF776 lies in its ultra-low noise figure—with a typical minimum noise figure of just 0.8 dB under operating conditions of 1.8 GHz, 3 V and 5 mA. This specification makes it the device of choice for RF front-end designs with stringent noise performance requirements.
