LTE21015R - NPN microwave power transistor

Description

DESCRIPTION NPN silicon planar epitaxial microwave power transistor in a SOT440A metal ceramic flange package with the emitter connected to the flange.

Fig.1 Simplified outline and symbol.

Features

  • Interdigitated structure provides high emitter efficiency.
  • Diffused emitter ballasting resistors provide 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 matching cell allows an easier design of circuits.
