NPN microwave power transistor LWE2010S
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.
APPLICATIONS
Common emitter class A power
amplifiers at frequencies up to
2.3 GHz.
DESCRIPTION
NPN silicon planar epitaxial
microwave power transistor in a
SOT446A metal ceramic flange
package, with emitter connected to
flange.
QUICK REFERENCE DATA
