PLB16004U - Microwave power transistor

Description

DESCRIPTION NPN silicon planar epitaxial microwave power transistor in a SOT437A glued cap metal ceramic flange package, with base connected to flange.

Fig.1 Simplified outline and symbol.

Features

  • Diffused emitter ballasting resistors improve excellent current sharing and withstanding a high VSWR.
  • Interdigitated common-base structure provides high emitter efficiency.
  • Gold metallization with barrier realizes very stable characteristics and excellent lifetime.
  • Multicell geometry gives good balance of dissipated power and low thermal resistance.
  • Internal input and output prematching networks allow an easier design of circuits.
