Philips Semiconductors Product specification UHF power transistor BLU45/12

DESCRIPTION

N-P-N silicon planar epitaxial transistor in SOT-119 envelope primarily intended for use in mobile radio transmitters in the 470 MHz communications band.

FEATURES

• multi-base structure and emitter-ballasting resistors for an optimum temperature profile.
• internal matching to achieve an optimum wideband capability and high power gain.
• gold metallization ensures excellent reliability. The transistor has a 6-lead flange envelope with a ceramic cap. All leads are isolated from the flange.
