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.

This ebook covers the filtering challenges and design tradeoffs for 5G plus some of the newer technologies being developed to handle the wider bandwidths and higher frequencies that will be required for 5G. The articles focus on the following topics: • Challenges and design tradeoffs to address the 5G market (including solutions that address the mmWave frequencies) • Design of a 28 GHz bandpass filter for 5G including simulation and port tuning techniques • Tolerance and size analysis for mmWave filter manufacturing • Challenges of designing a global 5G handset • New entrants into the SAW/BAW market • Reducing the cost and complexity in 5G mmWave systems with surface mount filter components

New satellite and military communications systems plus 5G cellular communications will require much larger bandwidth signals in the hundreds of MHz versus current systems using tens of MHz of bandwidth, so new semiconductor amplifier designs need to support these wider bandwidth signals. However, designing and testing these types of devices is challenging. This eBook addresses some of the design and test challenges plus provides some solutions for wider bandwidth amplifier design and test giving RF/microwave designers better insight in this area.

BIS Research analysis estimates the global autonomous vehicle market was valued at 6.6 million units in 2017 and is expected to reach 67.5 million units by 2028, registering a CAGR of 20.78% between 2018 and 2028. A critical sensor in the autonomous suite is the radar module currently being used for ADAS applications in many cars. This eBook addresses many of the design challenges for radar sensors with articles covering the effects of materials on 77 GHz radar modules, interference challenges in urban environments, testing challenges, and PCB materials solutions to the thermal and high frequency effects.
