The appetite for high data rate and ubiquitous terrestrial connectivity has stimulated huge investment in low Earth orbit (LEO) constellation systems. Low orbit significantly reduces launch and equipment costs, cuts latency by 20× compared with GEO links, and manages bandwidth and users more efficiently.

The demand for increased bandwidth in data communications is continually increasing, and the integrity of RF signals has become a major design concern. In broadband bias applications, most inductors do not cover enough impedance bandwidth. This paper discusses the proper use of broadband chokes in bias tees and critical design considerations including frequency range, DC resistance and current requirements.

In the last decade, the satellite communications (SATCOM) market has redefined the opportunity and the differentiator for this segment. Early business models that relied on providing voice services to the most remote areas of the globe have evolved to demonstrate how SATCOM can play a significant role in augmenting and improving terrestrial network connectivity. Component and system suppliers are excited because market research firms estimate the opportunity to be $50 to $70 billion by 2032. Including service revenue from applications that SATCOM capabilities will enable pushes these market opportunities to $200 billion in 2032, with the CAGR expected to be around 10 percent. With the “direct-to-device” opportunity of connecting cellular devices directly to satellites just emerging, there is a tremendous upside to these forecasts.

Learn about SIGLENT’s newest high-resolution oscilloscopes bring high fidelity signal quality to measurements from 70 MHz to 4 GHz with our newest additions. The SDS800X HD, SDS1000X HD and SDS3000X HD join the recently launched SDS7000A to bring improved signal fidelity to customer applications.

This eBook offers a comprehensive overview of the challenges, techniques and solutions for OTA measurements in the mmWave frequency range. The first article is a tutorial on the basics of OTA testing for 5G NR mmWave radios, likely the single most significant contributor to the scale and growth of the mmWave market. The following two articles look at semiconductors in the sub-THz and THz bands that overlap or are adjacent to the mmWave band. The first describes measurement setups and techniques for on-wafer testing. The second of these two articles describes generating signals and measuring devices in the “THz gap” of 100 GHz to 1 THz, where signals transition from electrical to optical. The fourth article in the eBook is an application note that amplifies this theme with the motivation, test setups and test methods for mmWave signal generation and analysis. The fifth article introduces techniques for designing and optimizing a compact antenna range (CATR) for the best OTA temperature tests. The seventh article proposes a test system containing multiple CATRs to enable OTA measurement of multiple angles of arrival. The sixth article and the final article are also application notes. The sixth article presents an overview of how to calculate a link budget for an OTA system and the final article presents an overview of the fundamentals of OTA power measurements.

In today’s high-performance electronic systems, power integrity (PI) has become a critical design and operational factor. With the increasing complexity of circuits, higher frequencies, and shrinking geometries, ensuring stable and clean power delivery across all components is essential. Unstable power supplies can result in signal integrity issues, degraded performance, or even system failure.

This eBook aims to serve as a resource for engineers, designers, and technical professionals looking to understand and improve power integrity in their systems by covering some new topics in this area. The articles cover interconnect requirements for power integrity testing, measuring high output voltage regulator noise, advanced power integrity measurement solutions, why measuring only board-level power rail noise may be misleading, and solving PI problems in FPGA systems.

Power supply measurements of ripple and noise are more important than ever as they impact system aging, reliability, and efficiency. High bandwidth, high resolution oscilloscopes, advanced power rail probing, and integrated FFT analysis improves accuracy and simplifies debugging of modern power signals. Learn about SIGLENT’s power rail measurement solutions.

DoD software teams have increasingly migrated to Development, Security, and Operations (DevSecOps) and this approach works very well when software is deployed on standard devices. When the hardware platform is custom and developmental, however, DevSecOps teams tend to need help. Learn how Benchmark bridges this gap by deploying tools and processes that enable the hardware to evolve throughout the program.

Balancing the performance and cost of antenna measurement RF sub-systems is an important part of the design process. Small or low frequency systems often use a centrally located vector network analyzer without any remotely installed RF electronics. As these systems get larger or the frequency increases, the need to locate RF components remotely to maximize the available dynamic range grows.

Featuring a curated collection of articles and papers spanning several years, the eBook, "A Practical Guide to Load Pull Measurements," is a comprehensive resource that covers critical load pull methods, applications, and measurement setups. From fundamental concepts to advanced techniques, learn how load pull optimizes the performance of RF/microwave systems.
