Product specification

UHF power transistor

BLU97

DESCRIPTION

N-P-N silicon planar epitaxial

transistor designed for use in mobile

radio transmitters in the 470 MHz

band.

FEATURES

• multi-base structure and

emitter-ballasting resistors for an

optimum temperature profile.

• gold metallization ensures

excellent reliability.

The transistor has a 4-lead stud

envelope with a ceramic cap

(SOT122A). All leads are isolated

from the stud.
