Philips Semiconductors
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.
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
PIN CONFIGURATION
PRODUCT SAFETY This device incorporates beryllium oxide, the dust of which is toxic. The device is entirely
safe provided that the BeO disc is not damaged.
