Product specification
NPN microwave power transistor
LV2024E45R
FEATURES
Interdigitated structure provides high emitter efficiency
Diffused emitter ballasting resistor provides excellent
current sharing and withstanding a high VSWR
Gold metallization realizes very stable 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.
APPLICATIONS
Common emitter class-A amplifiers in CW conditions for
military and professional applications in the
2 to 2.4 GHz band.
DESCRIPTION
NPN silicon planar epitaxial microwave power transistor in
a SOT445A metal ceramic flange package with the emitter
connected to the flange.
