BLV45-12
BLV45-12 is VHF power transistor manufactured by Philips Semiconductors.
- Part of the BLV45 comparator family.
- Part of the BLV45 comparator family.
DESCRIPTION
N-P-N silicon planar epitaxial transistor primarily intended for use in mobile radio transmitters in the 175 MHz mmunications 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. QUICK REFERENCE DATA R.F. performance up to Th = 25 °C in a mon-emitter class-B circuit MODE OF OPERATION narrow band; c.w.
