Product specication
NPN microwave power transistor
RX1214B300Y
FEATURES
Interdigitated structure provides high emitter efficiency
Diffused emitter ballasting resistors providing excellent
current sharing and withstanding a high VSWR
Gold metallization realizes very stable characteristics
and excellent lifetime
Multicell geometry improves power sharing and reduces
thermal resistance
Internal input and output matching networks for an easy
circuit design.
APPLICATIONS
Common base class-C wideband amplifiers operating
under pulsed conditions, recommended for L-band
radar applications.
DESCRIPTION
NPN silicon planar epitaxial microwave power transistor in
a SOT439A metal ceramic flange package with the base
connected to the flange.
