The New Space market is growing fast, and LEO Satellite Systems require the latest RF technology for communications and data transmission. This eBook covers the latest in LEO constellations and RF technology for power amplifier and components. The first two articles cover Ka-Band amplifiers and how GaN is changing the RF front end. GaN technology offers more efficient power solutions, opening up new ways to configure systems to reduce power consumption and heat dissipation. Other articles review the broadband satellite market, GlobalStar LEO Satellite System, Kuiper’s terminals, and the use of COTS components for Space applications.

With direct-to-satellite connectivity, unmodified cellular smartphones and IoT devices can now leverage satellite communications networks. These new capabilities will meet the needs of many applications for connectivity in remote areas where cellular service is unavailable while supplementing them in areas with cellular service already available. This eBook looks at various satellite communications trends along with the challenges and solutions related to device and system simulation and testing for these markets. Keysight Technologies, the sponsor of this eBook, presents end-to-end capabilities for testing and evaluating devices, subsystems, and systems for the growing satellite market.

The Cables & Connectors Special Focus section from the March Test & Measurement issue has been made into this eBook with articles covering the RF SMP board to board connector market review and RF interconnect requirements for high performance quantum computing technologies. There are also product feature articles and a new products section with the latest solutions for high frequency applications.

This eBook covers several design trends and technologies with high linearity devices ranging from switching to power amplifiers to complete systems. The first two articles cover new RF SOI device technologies addressing 5G MIMO and mMIMO systems. The next article looks at what the perfect HF receiver look like today - one that combines all available technologies into the most modern concept of a software-defined receiver. The next article covers Improving Linearity of a Doherty Power Amplifier with a Dual-Bias Structure. The article after that continues to cover integrated PA topologies for 5G mMIMO. 5G NR RF front end design engineers can benefit from understanding these trends and aspects of the new RF hardware and technologies needed to address the new challenges of 5G, so the next article covers these aspects. Finally, the capabilities and impact of new SOI tunable filter ICs on the design of the RF chains of phased arrays are discussed.

Filters are a critical component in any wireless system and in many the most numerous devices in the signal chain. There are many types of filters and even more ways of realizing them in with various processes and materials. This eBook from Knowles, reviews the basics of filter methods and types plus the critical performance parameters. By providing this detailed fundamental filter information, we hope to help you simplify your future filtering decisions.

Continuing improvements in radar system capabilities enabled by digital architectures are imposing new testing requirements and more capable measurement systems. This eBook explores this system trend and the implications for test and measurement systems. Topics include the continuing evolution of radar, advanced multi-mode multi-mission software-defined mmWave radar, heterogeneous Integration enables direct conversion RF to digital processing at the tactical edge, choosing the right GaN package for long pulse radar modes, plus several testing related articles such as signal generation for radar system testing, testing secondary surveillance radar, and measuring GaN PA linearity.

This eBook provides practical considerations for PCB design, given the central role PCBs play in virtually all components. The articles discuss the unique thermal challenges posed by mmWave active phased arrays, the theory of heat flow and the importance of PCB thermal conductivity, dielectric constant, dissipation factor and their respective changes with temperature, how the temperature variation of these parameters affects the response of a bandpass filter, long-term reliability, and short-term thermal stresses on PCBs caused by manufacturing process.

Qorvo has long been known for its RF capabilities, particularly its strength in power amplifiers based on GaN technology, which provides higher power density with high efficiency. Traditionally, RFIC companies haven’t worried about how their semiconductor components are biased, specifying a voltage and current in the data sheet and leaving procurement of the power supply to their customers. Yet the performance of the power supply affects the overall performance of the system: size, weight, efficiency, noise. So, it was logical that Qorvo expanded its product strategy to include power management. This eBook surveys Qorvo’s expanded portfolio for high performance analog applications.

This eBook explores the innovative automotive systems that use RF, microwave and mmWave technology and addresses some of the challenges testing them. Topics covered include UWB, C-V2X testing, radar development, integrated radar-bumper assembly test, 3D waveguide antennas for radar, target simulation, production testing of automotive radar, and new 4D imaging radars with the performance required to enable autonomous vehicles.
