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).

Whether prompted by the convenience of small size, the fuel savings from lighter weight or the smaller wavelengths of higher frequencies, size is on an inexorable decline. Moore’s Law is the archetype defining the shrinking of semiconductor technology, yet it would not be possible without other components following the same trend, particularly the passive devices that filter and route the signals processed by the ICs. This eBook compiled by Knowles explores some of the market and technology trends driving the demand for higher frequencies and smaller size. Beginning with an overview of the classic Wilkinson power divider and combiner designs, it also covers various other SATCOM related component technologies ranging from PCBs to high speed converters to phased arrays plus test challenges in this area.

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.

With advances in digital signal processing techniques modern wireless communications systems and radar systems have become increasingly digital and more constraints have been placed on packing more information into less and less bandwidth. On the wireless side, modulation formats have become more complicated with less margin for symbol error.

The focus of this white paper is on the general challenge of antenna design and simulation as implemented with antenna-in-package (AiP) and antenna-in-module (AiM) advanced packaging technology, as well as the software tools necessary for antenna, antenna array and feed structure, and front-end simulations.
