Features

  • Interdigitated structure provides high emitter efficiency.
  • Diffused emitter ballasting resistor provides 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.
  • Internal input and output prematching ensures good stability and allows an easier design of wideband circuits.
