Advancements within the telecom industry and digital communication methods complicate an RF measurement system’s capability to accurately characterize system components. This resource reviews how the air interface layer has changed throughout this digital evolution and explains how measurement systems often need to be upgraded to meet the new performance criteria.

Positioning technologies will continue to play an essential role in wireless communications. The influence of these technologies is transitioning to a “must-have” approach requiring resilient and reliable provisioning of location estimates. Register now for a concise description of 5G-relevant positioning technologies, related test challenges and how to solve them.

Imagine if it was possible to build multi-channel microwave radio systems leveraging optical rather than copper interconnects. Several benefits of this paradigm shift seem likely to follow including:

• Streaming sample, control & configuration data, as well as reference clock and synchronization signals via fiber simplifies radio front-end design, signal distribution whilst simultaneously reducing cable mass
• Eliminating copper signal wiring in future radio designs offers increased architectural freedom and flexibility whilst reducing crosstalk and inter-channel interference for better performance.
• The optical concept substantiates a valuable separation of front-end analog design from back-end digital signal processing heralding the arrival of fully digital antennas with enhanced operation arising from advanced electronic beam steering.

In this article, a comparison focused on the power efficiency of analog, digital, and hybrid beamforming architectures is presented. A detailed equation-based model for the power consumption of the three architectures was developed for a receive phased array. The model clearly illustrates the contributions of various components to the total power consumption and how the power scales with various array parameters. A comparison of power consumption per beam-bandwidth product for the different array architectures shows the advantage of the hybrid approach for millimeter wave phased arrays with a large number of elements.

This educational note provides performance parameters to consider when evaluating signal generators for your receiver testing in order to ensure that the signal generator provides a level of performance that has minimal effect on your receiver measurements.

Traditional fabrication approaches of Microwave/mmWave devices have material, geometry, tolerance, and/or repeatability challenges. New 3D printable resins with desirable Microwave/mmWave characteristics are enabling 3D DLP manufacturing of low-loss and low-dielectric constant material for prototyping and production. This whitepaper discusses applications of this 3D dielectric structure fabrication process.

For reliable and efficient system YOUR TASK verification and debug of DDR3/DDR4 memory designs, comprehensive compliance test and analysis tools are required. While measurement capability and usability are critical to speed up the verification and debug process, it is equally important to choose the right probing solution and use advanced techniques to improve overall measurement accuracy.

As the demand for higher frequencies and wider bandwidths continue their relentless march upward, RF connectors need to keep up with, or even exceed, demands. Mating the RF connector to a PCB or substrate requires careful consideration of several factors to get the full performance out of the connector. This white paper will provide an understanding of what makes successful launches work, what knobs to turn, and design guidelines to make connector launches perform well as the industry moves toward 100 GHz bandwidths.

The objective of this Rohde & Schwarz white paper is to provide a concise technology overview of 5G non-terrestrial networks with the author's background based on the wireless ecosystem.

Antenna tuners in smartphones, like other electronic components, must be able to withstand electrostatic discharge (ESD) at every stage from device manufacturing and smartphone assembly to consumer use. Rather than rely on legacy assumptions, tuner selection should reflect the manufacturing systems and standards of today. Learn more to protect your devices.
