PTB23002U - NPN microwave power transistor

Description

NPN silicon planar epitaxial microwave power transistor in a SOT440A hermetically sealed metal ceramic flange package, with base connected to flange.

QUICK REFERENCE DATA Microwave performance up to Tmb = 25 °C in a common-base class C narrowband amplifier.

Features

  • Very high power gain.
  • Internal input prematching network.
  • Diffused emitter ballasting resistors improve ruggedness.
  • Interdigitated emitter-base structure.
  • Gold metallization with barrier layer to prevent electromigration and gold diffusion during life.
  • Multicell geometry improves power sharing and reduces thermal resistance.
