UHF power transistor
Product specification
BLU20/12
DESCRIPTION
N-P-N silicon planar epitaxial transistor 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
• gold metallization ensures excellent reliability.
• internal matching to achieve an optimum wideband capability and high power gain.
The transistor has a 6-lead flange envelope with a ceramic cap (SOT-119). All leads are isolated from the flange.
