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.
