Spectrum clearance in mobile networks is becoming ever more important as operators use new bands that previously contained other services. This is particularly important for the 5G NR rollout. 5G NR has already initiated a worldwide deployment of TDD networks in an unknown radio environment where unwanted transmitters can create uplink interference masked by downlink signals, making interference hunting particularly demanding. Automated detection of interference signals before a network switches on can be a big help in addition to traditional manual techniques.

Stable operation in all circumstances is essential for power converters. Different working conditions, such as load steps, startup/shutdown sequences and input voltage variation, apply to most converter types. In addition to the standard feedback control loop, integrated pulse width modulation (PWM) controllers provide extended functions, such as line feed-forward loop control and soft-start control. These extended control functions improve regulation for specific conditions. Such complex regulation systems require smart methods to ensure proper operation of the converter in all modes. For this task, extensive expertise and the right measurement tools are essential for identifying and locating unexpected events in the system.

Automotive radar sensors can be well hidden behind bumpers, but require to be transmissible in the respective frequency domain. To effectively hide the sensors, the radar-transparent areas are usually required to have the exact same shade of color as the rest of the vehicle. To select proper colors and coatings for such bumpers, the respective material properties must be known. In the past, either quasioptical or waveguide based setups, both using vector network analyzers (VNA), have been used. This application card demonstrates a simplified method for material characterization in the automotive radar frequency domain (76 GHz to 81 GHz) based on the R&S®QAR50 automotive radome tester.
