Product specification
UHF linear push-pull power transistor
BLV862
FEATURES
Double stage internal input and output matching
networks for an optimum wideband capability and
high gain
Polysilicon emitter ballasting resistors for an optimum
temperature profile
Gold metallization ensures excellent reliability.
APPLICATIONS
Common emitter class-AB operation in output stages in
bands 4 and 5 (470 to 860 MHz) television transmitter
amplifiers (vision or sound).
DESCRIPTION
NPN silicon planar epitaxial transistor with two sections in
push-pull configuration. The device is encapsulated in a
SOT262B 4-lead rectangular flange package, with two
ceramic caps.
