The fundamental construction of a sensor node working in the 24 GHz Industrial, Scientific and Medical band (ISM) is presented. A brief overview of the electrical and technological design ideas is given. A small high efficiency solar cell is used for continuously powering the system allowing nonstop data logging of sensor data. The wireless read out procedure is accomplished by back scatter modulation...
In this contribution a 10 Watt gallium nitride (GaN) based inverse class-F power amplifier with an adaptive matching network realized with MEMS (micro electro mechanical systems) is presented. The developed power amplifier uses an adaptive output matching network for the enhancement of the power added efficiency over the dynamic output range. With the output matching network an efficiency enhancement...
This contribution presents a novel design concept of a 24 GHz radio frequency communication module. The integration of optical and electrical components is a particular challenge since the module is miniaturized in order to be integrated into any metallic workpieces. The design concept and the scope of functions of the communication unit acting as a wireless sensor node are discussed. The development...
