BFQ68 Datasheet, PDF (2/10 Pages) NXP Semiconductors – NPN 4 GHz wideband transistor

Philips Semiconductors
NPN 4 GHz wideband transistor
Product specification
BFQ68
DESCRIPTION
NPN transistor mounted in a four-lead
dual-emitter SOT122A envelope with
a ceramic cap. All leads are isolated
from the stud. Diffused
emitter-ballasting resistors and the
application of gold sandwich
metallization ensure an optimum
temperature profile and excellent
reliability properties. It features very
high output voltage capabilities.
It is primarily intended for final stages
in MATV system amplifiers, and is
also suitable for use in low power
band IV and V equipment.
