UHF power transistor
BLU99
BLU99/SL
DESCRIPTION
N-P-N silicon planar epitaxial
transistor primarily intended for use in
mobile radio transmitters in the u.h.f.
band. The transistor is also very
suitable for application in the
900 MHz mobile radio band.
FEATURES
» multi-base structure and diffused
emitter-ballasting resistors for an
optimum temperature profile;
• gold metallization ensures
excellent reliability.
The BLU99 has a 4-lead stud
envelope with a ceramic cap
(SOT122A). All leads are isolated
from the stud. The BLU99/SL is a
studless version (SOT122D).
