BFS480 is an NPN silicon RF transistor designed for low noise, low-power amplifiers in mobile communication systems such as pagers and cordless telephones. It operates at collector currents ranging from 0.2 mA to 8 mA, with a transition frequency (fT) of 7 GHz and a gain (F) of 1.5 dB at 900 MHz. The package contains two internally isolated transistors.
