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.

RF coaxial connectors and cables provide vital RF links in communications, broadcast, EMC testing, commercial, military, and test & measurement. In this guide, you will learn the different types of RF Coaxial Connectors and Cables, the various uses for each, and how to choose connectors best suited for your application.

Third order intercept (IP3) is a hypothetical point at which the fundamental signal power and the third order signal power is the same. In practice, we can never reach this point as the amplifier saturates even before this condition occurs. However, IP3 plays an important role in characterizing the device.

Read this white paper to learn more on over-the-air (OTA) testing on 5G NR devices. Focusing on RF conformance aspects and UEs, the paper examines the requirements described in the technical specifications. You will learn about antenna measurement key parameters, test methods and setups, and 3GPP OTA testing for UEs.

The spectral environment is quickly changing today. It’s becoming more crowded, which is resulting in an increase in spectral noise. This is presenting a variety of new challenges for RF designers, both in terms of the architecture and power needed to transmit and receive signals and the types of jobs filters need to perform in receivers (Rx) and transmitters (Tx).

Ultra-wideband (UWB) will be a game changing wireless communications technology. Learn the fundamental principles that have optimized it for secure micro-location-based applications. Discover UWB’s key features, different topologies used in UWB applications, and the main consortiums/alliances working to ensure interoperability and scalability of UWB products.

Non-terrestrial networks play a critical role providing service to locations not covered by terrestrial 5G networks. This paper describes the modeling of a SATCOM link, specifically how satellite coverage can be modeled using predictive simulation to capture important effects such as terrain masking, shadowing due to foliage, and multipath fading, which are essential to a proper evaluation of the link budget.

IEEE 802.11ax is intended to improve the user experience and network performance in dense deployments in the unlicensed bands. Explore the technology and get an overview of receiver and transmitter test requirement. Learn about the main goals and features of IEEE 802.11ax, the high efficiency PHY, and test requirements.

Without question, the rise of 5G has changed the landscape of wireless testing. One of the biggest changes is the ability of test engineers to perform over-the-air (OTA) testing without connecting anything or having a special setup. This is something that was not historically possible with past generations of wireless devices, as a result of FCC regulation and spectrum licensing law.
