LLE18300X Datasheet, PDF (2/12 Pages) NXP Semiconductors – NPN microwave power transistor

Philips Semiconductors
NPN microwave power transistor
Product specification
LLE18300X
FEATURES
Diffused emitter ballasting resistors
providing excellent current sharing
and withstanding a high VSWR
• Interdigitated structure provides
high emitter efficiency
• Gold metallization realizes very
good stability of the characteristics
and excellent lifetime
• Multicell geometry gives good
balance of dissipated power and
low thermal resistance
• Internal input and output
prematching ensures good stability
and allows an easier design of
wideband circuits.
