INTRODUCTION
   Freescale Semiconductor’s General Purpose Amplifier (GPA) devices are all designed to operate from a single positive voltage supply. The GPAs have output powers ranging from 12 to 34 dBm. They are currently designed with three different circuit techniques:

   • Darlington Pair
   • Discrete with integrated current mirror
   • Field Effect Transistor (FET) operating at zero gate voltage
      drain leakage current (IDSS)
   and use two different device technologies:
   • Indium Gallium Phosphide Heterostructure Bipolar
      Transistors (InGaP HBT)
   • GaAs Heterostructure Field Effect Transistor (HFET)
