DESCRIPTION
The BFXS9 and BFY90 are silicon planar epitaxial
NPN transistors produced using interdigitated base
emitter geometry. They are particulary designed for
use in wide band common-emitter linear amplifiers
up to 1 GHz. They feature very high fr, low reverse
capacitance, excellent cross modulation properties
and very low noise performance. The BFY90 is com-
plementary to the BFR99A. Typical applications in-
clude telecommunication and radio communication
equipment.
