General Purpose Amplifier Biasing by: Jeff Gengler Freescale Semiconductor
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...
