Microwave power transistor

NPN silicon planar epitaxial microwave power transistor in a 2-lead rectangular flange package with a ceramic cap (SOT423A) with the common base connected to the flange.

Features and benefits

  • Emitter ballasting resistors improve ruggedness
  • Gold metallization ensures excellent reliability
  • Interdigitated emitter-base structure provides high emitter efficiency
  • Internal input and output matching networks for an easy circuit design
  • Multicell geometry improves power sharing and reduces thermal resistance
  • Suitable for short and medium pulse applications

Applications

  • Common base class-C pulsed power amplifiers
  • Radar applications in the 2.7 to 3.1 GHz band
