VHP LINEAR PUSH-PULL POWER TRANSISTOR
Two NPN silicon planar epitaxial transistor sections in one envelope to be used as a push-pull amplifier.
This device is primarily intended for use in linear VHP television transmitters and transposes (vision or
sound amplifier).
Features
Internally matched input for wideband operation and high power gain
Internal midpoint (RF ground) reduces negative feedback and improves power gain
Increased input and output impedance (compared with single-ended transistors) simplify wideband
matching
Length of external emitter leads is not critical
Diffused emitter balancing resistors for an optimum temperature profile
Gold metallization ensures excellent reliability
The envelope is an 8-lead flange type with a ceramic cap. All leads are isolated from the flange.
