Is RF engineering a form of black magic? This article analyzes the challenges faced in the development of ADH519S, an 18 GHz to 31 GHz low noise amplifier (LNA), for the aerospace market. The die used in the product development for space was originally released to the commercial industry in the LC4 package.

In this paper, TE Connectivity (TE) will examine smart meters—a key part of the smart grid ecosystem—and describe the market growth factors, technology trends, applications and features to consider.

Want to discover antenna measurement key parameters and over-the-air (OTA) test methods and setups? Read this white paper to learn more on the technical background for OTA testing on 5G NR devices. Focusing on RF conformance aspects and UEs, the paper examines the requirements described in the technical specifications.

Many consumer products communicate over broadband networks. From television to fiber transmission networks, the bandwidth of data communication is increasing, and the integrity of RF signals has become a major concern. This paper demonstrates how inductors are used for RF isolation in circuits ranging from relatively narrow band applications like portable devices up to broadband networks for data distribution.

This eBook surveys the state of GaN and its use for 5G base stations, concluding with the day when GaN will be eyed for 6G systems operating at E-Band and above. The first article reviews the growth of GaN since Strategy Analytics began tracking it in 2007. Strategy Analytics forecasts continued growth driven by strong defense and 5G demand. The next article discusses DPD linearization challenges for 5G transmitters. A relevant example of GaN’s broadband capabilities is presented in a design article of a 10 W nominal PA covering 1.4 to 3.6 GHz, achieving 60 to 68 percent drain efficiency and adjacent channel power ratio better than −30 dBc. The eBook concludes with an application note on making accurate device load-pull measurements from 70 to 110 GHz. Accurate load-pull data is a key element of successful PA design, and while E- and W-Band frequencies may not seem relevant to today’s cellular PA designers, it won’t be long.

The use of machine learning enables an antenna designer to generate a trained mathematical model that replicates an original antenna design. The trained model enables the optimization of the antenna through thousands of iterations in just a few seconds.

There have a been a lot of developments in the Electronic Warfare (EW) and Signals Intelligence markets in the last few years as higher power, wideband hardware has become more mainstream and artificial intelligence (AI)/machine learning (ML) have advanced on the software side. This eBook reviews some of the recent advances in smarter, more flexible hardware to gather and jam signals from these emerging threats. The first couple of articles review the state of EW and how AI and ML are enabling new solutions. The next article covers open system architectures for military applications and how they are enabling next generation defense systems. The next two articles cover drone detection and defeat technologies starting with systems that can adapt to their environment followed by an article about emerging drone technologies. The last article briefly covers the RTX 2684 26 GHz RF Sentinel™ Intelligent Signal Scanning small form factor recorder.

Discover how ultra-fast data conversion and signal processing systems can be designed to guarantee deterministic latency. Past efforts focused on increasing data transmission speeds and bandwidths but increasingly, modern applications now set an equally high value on determinism. This article considers determinism, at device level and expands on the topic of how ultra-fast data conversion and signal processing systems can be designed to guarantee deterministic latency.

A discussion of noise figure measurements includes a wide number of options, instrumentation, and techniques each with their own advantages and limitations. In this tech brief, we focus on non-cryogenic applications, with proven performance, that can be conducted with standard laboratory equipment and easily followed by trained personnel.

Measurements of very high noise figure components are performed for a number of reasons. For instance, in a wide range of applications, devices under test (DUT) are characterized within a complex test setup that includes high losses before or after the low noise DUT.
