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
