Abstract (en)
[origin: WO2005114774A2] An electronic microwave circuit (1) with GaAs field effect transistors (15) integrated on a semiconductor substrate (5) for switching electric input high-frequency signals (16) has at least one light source (2) for illuminating the GaAs field effect transistors (15). The light intensity of the light source (2) and/or its colour can be modified during operation. A calibrating device (20) calibrates the light intensity and/or colour of the light source (2) according to the claimed process.
