BLU99

DISCRETE SEMICONDUCTORS DATA SHEET BLU99 BLU99/SL UHF power transistor Product specification March 1993 Philips Semiconductors Product specification UHF power transistor DESCRIPTION N-P-N silicon planar epitaxial transistor primarily intended for use in mobile radio transmitters in the u.h.f. band. The transistor is also very suitable for application in the 900 MHz mobile radio band. FEATURES multi-base structure and diffused emitter-ballasting resistors for an optimum temperature profile; gold metallization ensures excellent reliability. The BLU99 has a 4-lead stud envelope with a ceramic cap (SOT122A). All leads are isolated from the stud. The BLU99/SL is a studless version (SOT122D). QUICK REFERENCE DATA R.F. performance at Th = 25 °C in a common-emitter class-B circuit. MODE OF OPERATION narrow band; c.w. VCE V 12,5 12,5 f MHz 470 900 PL W 5 4 > typ.
