ABSTRACT:
An RF signal is transformed (12 and 12') to increase its current component, while reducing its voltage component below the voltage that would damage a GaAs switching device (16 or 16'). The current and voltage transformation are selected so that the power of the RF signal remains substantially constant. Subsequent to the GaAs switching device, the signal is converted (24 and 24') to increase the voltage component while decreasing its current component to substantially recreate the original RF signal.
