Abstract
PURPOSE: To decrease the capacity of emitter biasing power, by by-passing the emitter current on and after the emitter potential of a base common high frequency transistor (TR) is inverted to an opposite potential to the base potential, with the 2nd transistor.
CONSTITUTION: If a high frequency input is less, since the collector voltage of a TR13 is in an opposite potential, no current flows to the TR13. On the other hand, when the high freuquency input increases, the emitter current of a TR1 is increased, the emitter voltage VE at point A close to zero from a negative potential through the voltage drop across a resistor 8 and is inverted to a positive potential. After that, the emitter current further increased is by-passed through the TR13. This current does not become a load for an emitter bias power supply 12. The power supply 12 can be reduced for the capacity for the power loss' share, allowing to increase the overall efficiency of the amplifier.
