NPN 4 GHz wideband transistor
DESCRIPTION
BFQ34
PINNING
NPN transistor encapsulated in a 4
lead SOT122A envelope with a
ceramic cap. All leads are isolated
from the stud.
It is primarily intended for driver and
final stages in MATV system
amplifiers. It is also suitable for use in
low power band IV and V equipment.
Diffused emitter-ballasting resistors
and the application of gold sandwich
metallization ensure an optimum
temperature profile and excellent
reliability properties. The device also
features high output voltage
capabilities.
