NPN 5 GHz wideband transistor
DESCRIPTION
BFR92
PINNING
NPN transistor in a plastic SOT23
envelope primarily intended for use in
RF wideband amplifiers and
oscillators. The transistor features
low intermodulation distortion and
high power gain; due to its very high
transition frequency, it also has
excellent wideband properties and
low noise up to high frequencies.
