Description
NPN silicon planar epitaxial microwave power transistor in a SOT439A metal ceramic flange package, with base connected to flange.
It is mounted in common base configuration and specified in class C.
Features
- Interdigitated structure; 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 gives good balance of dissipated power and low thermal resistance.
- Input and output matching cell allows an easier design of circuits.
