NPN 7GHz wideband transistor
DESCRIPTION
NPN silicon planar epitaxial transistor
in a plastic SOT223 envelope,
intended for wideband amplifier
applications. The small emitter
structures, with integrated
emitter-ballasting resistors, ensure
high output voltage capabilities at a
low distortion level.
The distribution of the active areas
across the surface of the device gives
an excellent temperature profile.
