Wireless Communications for Automotive Applications

This white paper examines everything from lab-based testing and in-field performance testing to over-the-air (OTA) testing needs for vehicles. In the end, a clear overview of supplementary, non-communication related testing aspects in the automotive world is offered.

Faster Testing of Phased Array Antennas Improves LEO HTS Launch Rates

Understand the benefits of multi-probe technology for the faster testing and calibration of phased array antennas in LEO HTS, improving time-to-market and speed of production in the race to deliver viable connectivity on a global scale.

Generation of Radar Signals in a Hardware in the Loop (HIL) Environment

This application note belongs to a series of application notes which explain how to test EW receivers at RF in the lab with commercial, off-the-shelf signal generators and software. The series will cover all relevant use cases. This application note will discuss the generation of radar signals in a hardware in the loop (HIL) environment with PDW streaming.

Designing BUC/SSPAs for Airborne Applications

As we witness the evolution of integrated communication, we also observe the increased number of requirements for airborne microwave transmission, ranging from satellite to air-to-ground CDL band communications. Airborne applications introduce many challenging design constraints including increased temperature ranges, thermal management, vibration and shock, EMC/EMI, power requirements, and safety, all while maintaining portability as a key factor.

Reliable and Flexible Simulation of Angle of Arrival (AoA)

Engineers often need to test the direction finding capabilities of radar warning receivers in the lab. A perfect solution is to use multiple coupled R&S®SMW200A vector signal generators that are phase-coherent and time-synchronized. This setup enables simulation of the angle of arrival (AoA) of radar signals in the lab.

Millimeter-Wave Receiver Calibration Made Easier, Cheaper, and Faster

Keysight’s new RCal helps you easily calibrate out errors from your measurement setup, improving your test Rx system accuracy by 10X. See the true performance of your device by moving your measurement plane from the signal analyzer input directly to the output of your device.

RF/Microwave Technology Driving the Connected Car

In-car networks and advanced driver-assist systems (ADAS) present many design challenges to engineers. This white paper looks at Cadence® AWR Design Environment® software solutions for RF to millimeter-wave (mmWave) front-end component development that address electronic product development for automotive applications.

NewSpace Terminal Testing Challenges and Considerations

Today’s satellite communication systems combine features from legacy cellular networks and emerging wireless technologies. New constellations are under development that attempt to provide ubiquitous mobility and internet networks via satellites, ground stations and user terminals (Figure 1). Each link in the supply chain presents unique challenges for R&D, production and deployment for both the components and system development.

Flying an Agile RF Transceiver in Space

ADI’s unique commercial space flow enables satellite bus and payload builders to integrate a modern solution rapidly that meets the specific needs of the newest generation of on-orbit space vehicles. Aside from the process, we’ll explain the rationale behind having two commercial space flows on the impacts on RF and Microwave products.

Application Note: Improving R&S®FSWP Measurement Speed

For automated test applications, measurement time is often as important as the quality of the measurement. In practice, phase noise measurements are generally not considered fast, but test engineers still desire to save as much test time as possible. With this paper you get a modern, digital signal processing based, phase-noise test set that performs many tasks in parallel in an effort to improve measurement speed.
