Philips Semiconductors
UHF power transistor
Product specification
BLV91/SL
DESCRIPTION
NPN silicon planar epitaxial transistor designed for use in
mobile radio transmitters in the 900 MHz band.
FEATURES
• diffused emitter-ballasting resistors for an optimum
temperature profile.
• gold metallization ensures excellent reliability.
• the device can be applied at rated load power, without
an external heatsink, when it is mounted on a
printed-circuit board (see Fig.6).
The transistor has a 4-lead envelope with a ceramic cap
(SOT-172D). All leads are isolated from the mounting
base.
