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.
