Product specification
NPN 5 GHz wideband transistor
BFR93AW
FEATURES
High power gain
Gold metallization ensures
excellent reliability
SOT323 (S-mini) package.
APPLICATIONS
It is designed for use in RF amplifiers,
mixers and oscillators with signal
frequencies up to 1 GHz.
DESCRIPTION
Silicon NPN transistor encapsulated
in a plastic SOT323 (S-mini) package.
The BFR93AW uses the same crystal
as the SOT23 version, BFR93A.
