Product specication
NPN microwave power transistor
RZ1214B65Y
FEATURES
Interdigitated structure provides high emitter efficiency
Diffused emitter ballasting resistor providing 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 matching ensures good
stability and allows an easier design of wideband
circuits.
APPLICATIONS
Intended for use in common base class C wideband
pulsed power amplifiers for L-band radar applications in
the 1.2 to 1.4 GHz band.
DESCRIPTION
NPN silicon planar epitaxial microwave power transistor in
a SOT443A metal ceramic flange package with the base
connected to the flange.
