Digitally driven, switched transistors are more and more THE core elements to push many areas of electronics to a new, higher level of development and thus make them future-proof. Fast and efficient switching enables the connection of power to high-frequency electronics (power meets RF). It provides more efficient power management capabilities and maximum flexibility as well as compactness for the infrastructure of future mobile communications from sub-6 to 300 GHz (5G/6G). The target is the complete digitization of the components. This paradigm shift will significantly preserve resources and reduce CO2 emissions – a decisive driver for the worldwide project of green communications technology (Green ICT). All these goals are being pursued by the Digital PA Lab, which is working on digital transmitters for various areas.
Our topics focus on different applications from 100 MHz ... 300 GHz. In all cases, highly efficient high speed switching is required as a difference maker to push performances.
