Today’s satellite communication systems combine features from legacy cellular networks and emerging wireless technologies. New constellations are under development that attempt to provide ubiquitous mobility and internet networks via satellites, ground stations and user terminals (Figure 1). Each link in the supply chain presents unique challenges for R&D, production and deployment for both the components and system development.

The paper reviews the qualities of high-performance crystal oscillators that make them the preferred solution over MEMS oscillators in applications where high-reliability under extreme conditions is not an option. 

With the continued advancement of ICs for the wireless industry, semiconductor companies once known only as component providers are now able to offer complete system solutions. This month we interview Analog Devices, a company unique in the industry, combining high-speed data converters with an extensive RF, microwave, and power portfolio.

The Rohde & Schwarz fundamentals are intended to familiarize the uninitiated reader with the field of spectrum analysis. To understand complex measuring instruments it is useful to know the theoretical background of spectrum analysis.

“High-performance, millimeter-wave MMIC products” and “cost-effective surface mount lead-frame-based packaging” typically don’t come up in the same conversation, and for good reason. Just two or three years ago, it was difficult to conceive of operating at frequencies above 20 GHz without considering an expensive, open cavity, HTCC package or resorting to more bespoke chip and wire assemblies.

There have been many advancements in RF compound semiconductors in the last few years. GaAs designers have developed higher performance products to compete with GaN and with the mainstreaming of GaN technology, some companies are taking it to the next level with higher power levels than ever imagined before. From improvements in performance and levels of integration to reliability and packaging, this eBook examines many of these new developments and will update you on several advancements in high frequency compound semiconductor technology.

Learn the pros and cons of various 5G OTA test systems and newly introduced StarWave, a compact, accurate and flexible far-field OTA testing solution for 5G devices. This compact and flexible, dual polarized, wideband plane wave generator turn-key test system was developed to improve testing efficiency and optimize time-to-market of 5G devices. The eBook covers the challenges of 5G OTA testing and compares compact antenna test ranges with plane wave generator based systems highlighting the advantages of each.

The increasing density of devices, machines, systems and vehicles using wireless connectivity solutions can pose a great challenge for a new Wi-Fi module due to the presence of interfering signals. A wireless receiver’s ability to receive a wanted signal in the presence of an interfering signal is described by blocking characteristics.

In the radio-frequency world, the term "direction finding" (DF) refers to the use of specialized instruments, antennas, and methodologies to determine the physical or geographical location of an emitter; that is, a source of radio-frequency energy.

This white paper provides an overview of test solutions addressing current and future requirements for antenna verification including both conducted and over-the-air test methods, which result from applying Massive MIMO antenna technology.
