Product specification
NPN microwave power transistor
PXB16050U
FEATURES
Input and output matching cells
allow an easier design of circuits
Diffused emitter ballasting resistors
providing excellent current sharing
and withstanding a high VSWR
Interdigitated structure provides
high emitter efficiency
Gold metallization realizes very
stable characteristics and excellent
lifetime
Multicell geometry gives good
balance of dissipated power and
low thermal resistance.
APPLICATIONS
Common-base class C power
amplifiers at frequencies between
1.5 and 1.8 GHz.
DESCRIPTION
NPN silicon planar epitaxial
microwave power transistor in a
SOT439A metal ceramic flange
package with base connected to the
flange.
