The final article discusses the benefits of Open RAN, a standardized approach to radio access network hardware and software disaggregation and how front-end reference designs can enable massive MIMO, which has become an essential. building block of the 5G future.
Microwave subsystems are complicated and have many tradeoffs in design. This is especially true with RF filter products. To help engineers navigate RF filter procurement, Q Microwave has created this comprehensive guide covering RF filter materials, configurations and packaging. This eBook reviews filter design, material selection, packaging, SWaP-C, and customization to meet unique needs.
This eBook addresses some of the challenges and best practices when designing and fabricating PCBs for RF applications. The first article gives a good overview of the fabrication process for a variety of different multilayer printed circuit boards. The second article provides insight into the reality of PCB fabrication versus the ideal models and how those differences become more important as circuits go higher in frequency. Article three acknowledges that these PCBs will operate at elevated temperatures, and it provides insight into the failure mechanisms, test methods and proper selection of substrate materials to optimize temperature performance. The fourth article provides good technical details about how to select the proper circuit board dielectric mate-rial as applications go higher in frequency. The final two articles address the finer points of the board design and manufacturing process for a microwave power amplifier and a microwave/millimeter wave patch antenna.
The need to address EMC/EMI problems has never been more pressing. As electronic devices become smaller, faster, and more powerful, the potential for interference grows exponentially. It's no longer sufficient to simply design and build electronic systems without considering their EMC/EMI characteristics. Engineers, designers, and technicians must proactively identify and mitigate these issues to ensure that their products meet regulatory standards, perform reliably, and avoid costly setbacks. This eBook provides an understanding of the underlying principles, practical methodologies, and advanced techniques for dealing with EMC/EMI challenges. It is designed for both newcomers seeking a foundational knowledge of the subject and experienced professionals looking to deepen their expertise.
This eBook explores several new trends in aerospace and defense. It covers a variety of topics including pulse droop in long pulse width, high-power, solid-state amplifiers used for radar and EW systems; how the creation of an air cavity in the PCB stack-up decreases the insertion losses of the traces and increases the antenna performance in the mmWave bands; discussion of supply chain security and counterfeit detection using universal chip telemetry; and the nuances of space level qualification and the screening process for these devices.
This eBook addresses some of the challenges and considerations when developing architectures and components to support these new multi-band, multi-services capabilities. The first article gives a good overview of multi-band microwave direct access using synthetic aperture radars using earth observation applications as an illustration. Articles two through four address how direct data converters and other components are enabling software satellites and other multi-band, multi-services transceivers. The final two articles explore using data converters and signal processing, in conjunction with optical interconnects to replace copper in the transport layer. We hope that this eBook gives you a good overview of the possibilities that can be enabled by high performance, direct access, multi-band, multi-services networks.
High-speed digital communications have been adopted so quickly because of a variety of performance advantages. The signals are quantized and may be encoded, making them less susceptible to noise and interference, which also increases the acceptable transmit range. Complex modulation schemes increase spectral efficiency, allowing for higher data rates and errors can be detected and corrected with processing. However, these communications networks must accurately reconstruct the sampled incoming signal, making timing synchronization critically important. This eBook focuses on jitter, simply defined as any effect that causes signal threshold crossing times to deviate from their expected positions. The first article addresses the inter-relationships between jitter and other noise-generating mechanisms. The second explains the types and sources of jitter and the third looks at how jitter propagates through the channel. The final six articles in this eBook show Skyworks’ broad portfolio of frequency flexible timing products along with how they compare to and can be incorporated with solutions from six different suppliers.
This eBook addresses some of the challenges of EMC testing in a variety of applications, with the first article addressing a method to speed up testing to improve throughput. The second article addresses some of the specific EMC challenges and solutions unique to e-mobility applications and the third article addresses the benefits of pre-compliance EMC testing. The final three articles in this eBook show how products and test methods from AR can help provide solutions. We hope that this eBook gives you a good overview of the importance of EMC testing along with some of the associated challenges.
