BLU45-12

DISCRETE SEMICONDUCTORS DATA SHEET BLU45/12 UHF power transistor Product specification August 1986 http://www.Datasheet4U.com Philips Semiconductors Product specification UHF power transistor 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. BLU45/12 The transistor has a 6-lead flange envelope with a ceramic cap. All leads are isolated from the flange. QUICK REFERENCE DATA R.F. performance up to Th = 25 °C in a common-emitter class-B circuit MODE OF OPERATION narrow band; c.w.
