UHF linear power transistor
BLW98
DESCRIPTION
N-P-N silicon planar epitaxial
transistor primarily intended for use in
linear u.h.f. amplifiers of TV
transposers and transmitters in band
IV-V, as well as for driver stages in
tube systems.
FEATURES:
diffused emitter ballasting resistors
for an optimum temperature profile;
gold sandwich metallization
ensures excellent reliability.
The transistor has a
1
4
" capstan
envelope with ceramic cap. All leads
are isolated from the stud.
QUICK REFERENCE DATA
R.F. performance in linear amplifier
Note
1.
Three-tone test method (vision carrier
8 dB, sound carrier
7 dB, sideband signal
16 dB), zero dB corresponds to
peak sync level.
