Top view handbook, 4 columns LFE18500X QUICK REFERENCE DATA Microwave performance up to Tmb = 25 °C in a mon emitter class AB amplifier.

MODE OF OPERATION Class AB (CW) f (GHz) 1.85 VCE (V) 24 ICQ (A) 0.2 PL1 (W) ≥48 Gpo (dB) ≥7 ηC (%) Z i ;

Key Features

  • Diffused emitter ballasting resistors providing excellent current sharing and withstanding a high VSWR.
  • Interdigitated structure provides high emitter efficiency.
  • Gold metallization realizes very good stability of the 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.
