This eBook is a compilation of phased antenna and beamforming technology articles along with contributions from COMSOL on simulation techniques and examples of new antenna arrays and beamforming techniques to help you learn about the tradeoffs and design options in this fast developing area. The articles cover fully digital phased array radars, modeling and simulation examples, new array beamforming technologies, 28 GHz beamsteering antenna array simulation and other related topics.

As the RF spectrum becomes more crowded, the chance for interfering signals greatly increases as frequency bands become very close to each other and sometimes even overlap. There are many techniques from filtering to spectrum sharing to frequency cancelation. This eBook has five articles that cover various aspects of interference. The first takes a look at the Wi-Fi or 5G question – do we need both and how they use the same frequencies in some cases. The second article looks at a new self-interference cancelation method for co-location of radio transceivers so they can share the same frequency band. The third looks at a growing technology for 5G called Dynamic Spectrum Sharing that allows LTE and 5G signals to use the same frequency band. The next article is a short discussion about how the unlicensed bands may become a key factor in the rollout of 5G. The last article takes a look at 5G mmWave filtering and the challenges to designing good filters at these higher frequencies.

As 5G, Wi-Fi 6 and various IoT connectivity standards roll out together, many people wonder how these technologies will work together to benefit businesses and consumers. This eBook presents a number of products and technologies that enable Wi-Fi, IoT and 5G wireless systems to work together without interference. New filter and front-end modules are key products that enable these wireless technologies to work together seamlessly. The first two articles feature Qorvo products that allow these wireless technologies to work together with excellent performance. This is followed by a short update on the release of Wi-Fi 6 and then a thorough article covering the various Wi-Fi and IoT deployment synergies.

This eBook covers almost everything you need to know about testing and verification for 5G from devices to systems from an RF perspective. Rohde & Schwarz authored most of these informational articles with Microwave Journal plus an additional article from Maury on load pull. The articles discuss important features of 5G such as spectral and energy efficiency along with Dynamic Spectrum Sharing; specific test solutions such as drone testing of 5G systems and on wafer load pull measurements at mmWave frequencies; testing and digital optimization for Doherty power amplifiers; and 5G test systems including a one box solution and hardware/software for 5G OTA testing.

Signal integrity is becoming more and more important as digital signal speeds and analog frequencies are rapidly increasing making circuits much more sensitive to any losses or variations in the path. This eBook provides information and instruction on making accurate signal integrity measurements with emphasis on the VNA as a tool. The articles cover TDR, VNA measurements, impedance measurements, uncertainly in S-parameter measurements and development of a 1.35mm connector for E-Band cable assemblies.

This eBook looks at some key applications where oscilloscopes are best suited to make the key measurements to evaluate your designs. The first article examines practical printed circuit board design and manufacture to reduce noise by comparing two simple circuits and the resulting difference in their performance. The next article looks at triggering on radar RF pulses with an oscilloscope. And another article follows covering demodulating radar RF pulses with an oscilloscope. Then the eBook shares some tips about how to successfully perform low noise, sub-milliOhm measurements in very small circuits, followed by making power integrity measurements with R&S®RTP oscilloscopes. The last article is about how Rohde & Schwarz has expanded its high-performance R&S RTP oscilloscope family in terms of both bandwidth, and functions for debugging and analysis.

This eBook is intended to help designers develop and test new radar sensor technologies as we have collected some of the latest articles in this area for this publication. The articles include a market overview, review of a new digital code modulation MIMO radar technology, a highly integrated 140 GHz FMCW radar for vital sign monitoring and gesture recognition applications, and several articles from test expert Rohde & Schwarz about measurement techniques for radar systems including optimizing beamforming from bits to RF beams, measurement of radar pulse stability and advanced methods for analyzing ultra-wide automotive radar signals.

This eBook addresses some of the challenges with design solutions that were published in Microwave Journal. Microlab looks at the challenges and solutions for network densification as small cells will need to be deployed in massive numbers to achieve 5G NR goals. The second article is written by Nokia about how microwave solutions are required to drive 5G deployment. Qorvo discusses the various technology tradeoffs for designing FWA arrays including beamforming techniques, front-end components and semiconductor materials. Lastly, Rohde & Schwarz looks at optimization techniques for Doherty power amplifier design as these are a prime choice for basestation applications.

This eBook takes a look at the importance of mmWave technology and the design considerations needed for antenna and system design. The first two articles discuss mmWave technology related to 5G NR systems. Then we look at antenna simulation for better design of systems using CDF to assess 5G antenna directionality. The last two articles cover the PCB material considerations for designing circuits at mmWave frequencies and takes a comprehensive look at the subtle effects that need to be understood to properly design systems.

This eBook looks at some of the innovative approaches to 5G phased arrays and the design/simulation to realize these products quickly. The eBook starts with an overview of the mmWave 5G market and technology approaches. Then efficient design and simulation techniques are covered to realize phased array designs. MathWorks then explores hybrid beamforming architectures for Massive MIMO 5G Systems including how use modeling and simulation to help reduce the risk associated with a complex workflow. Finally, several different architectures and approaches to 5G phased arrays are covered with solutions from IQ-Analog, SiverIMA, Gapwaves and StaixFy.
