UHF power transistor BLV97CE

FEATURES

• Internal input matching to achieve high power gain

• Ballasting resistors for an optimum temperature profile

• Gold metallization ensures excellent reliability

DESCRIPTION

NPN silicon planar epitaxial transistor in a SOT171
envelope, intended for common emitter, class-AB
operation in radio transmitters for the 960 MHz
communications band. The transistor has a 6-lead flange
envelope, with a ceramic cap. All leads are isolated from
the flange.
