New Developments in SATCOM
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.
The articles in this eBook give the reader a good understanding of the fundamentals and challenges of a satellite network, along with how the solutions will influence trends and opportunities. Electronically scanned phased array antennas are the foundation for NTN capabilities. Several of the articles address that application, along with system architectures and how to reduce component and system costs. Recognizing that SATCOM systems are trending higher in frequency, one of the articles addresses PCB design and development challenges and the best solutions for high-performance, low-cost millimeter wave circuits.
mmWave & OTA Measurements
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.
