Philips Semiconductors Product specification
HF/VHF power transistor BLW83
DESCRIPTION
N-P-N silicon planar epitaxial
transistor for use in transmitting
amplifiers operating in the h.f. and
v.h.f. bands, with a nominal supply
Matched h
request.
It has a 3/8" flange envelope with a
ceramic cap. All leads are isolated
from the flange.
groups are available on
FE
voltage of 28 V. The transistor is
specified for s.s.b. applications as
linear amplifier in class-A and AB.
The device is resistance stabilized
and is guaranteed to withstand
severe load mismatch conditions.
