Arbitrary waveform generators or AWG’s come close to being universal signals sources. They are digitally based devices capable of generating any waveform, within published limits of bandwidth, memory length, accuracy, and output level. Sixteen bits of amplitude resolution are available with bandwidths from 70 to 600 MHz and output levels as high as 24 Vpp.

In this paper we discuss a commonly asked question, “Why not just integrate a filter in the board stack?” Besides overall filter performance concerns, our answer to this comes in two parts: First there are manufacturing tolerances to consider, and second there is size.

The 5G test industry requires improved reliability of cable assemblies to help improve test outcomes. A significant portion of a test system’s stability and repeatability is determined by the precise performance of microwave/RF cable assemblies. Engineers should understand how cable assemblies affect the test system to maximize and optimize overall performance.

5G networks will need to offer more capacity and flexibility while lowering the operational expenses of the system. Two new technologies can simultaneously address both the increase in capacity and the increase in energy efficiency: Virtualization & Massive MIMO. The white paper provides an overview of test solutions addressing current and future requirements for antenna verification including both conducted and over-the-air (OTA) test methods, which result from applying Massive MIMO antenna technology.

This is the second article of our three-part series on phased array antenna patterns. In Part 1, we introduced the phased array steering concept and looked at the influencers on array gain. In Part 2, we’ll discuss grating lobes and beam squint. Grating lobes can be hard to visualize, so we’ll draw on their similarity with signal aliasing in digital converters, then use that to think of a grating lobe as a spatial alias.

While the world’s militaries increasingly rely upon seamless wireless communication networks for multi-domain battlefield readiness, protecting these mission critical networks from disruption and catastrophic failure becomes paramount.

The expansion of activities in the areas of SATCOM, automotive radar, 5G, security and others are pushing semiconductor technologies higher in frequency. The design of mmWave MMICs is much more difficult that those at lower frequencies as everything becomes much more sensitive in the design tradeoffs that affect performance. In this eBook we have collected some of the latest information on testing and designing mmWave MMICs to help in your selection and understanding of these devices.

This eBook covers a wide variety of current design and test challenges in the high frequency range from the lower to upper levels in the mmWave band. The first article is about using drones to measure satellite antennas in a more efficient and cost-effective way by avoiding transporting them to test facilities. The following article discusses the best semiconductor technologies for cellular applications about 90 GHz looking toward 6G. It compares the advantages and disadvantages of each platform. The next article compares several different packaging technologies for mmWave applications including cofired ceramic, antenna in package, fan-out wafer level packaging and PolyStrata®. Finally, the last article reviews the use of broadband free space methods for measuring dielectric materials at mmWave frequencies. These methods are coming under increased usage due to the increasing interest in 5G and mmWave sensing applications.

Realizing the global 5G vision depends on delivering efficient and powerful wireless connectivity – without that, the expectations and seemingly limitless ability of 5G are lost. And it is for that reason, best practice antenna testing of any 5G device, great or small, is to be optimized. This brochure explores the theme of effective, best practice 5G device testing with a keen focus on direct far-field testing to mark the launch of StarWave by MVG, a dual-polarized, wideband plane wave generator designed for flexible, fast and accurate direct far-field OTA testing of 5G antennas in a compact environment.

Ultra-Wideband (UWB) radio is defined as any RF technology utilizing a bandwidth of greater than ¼ the center frequency or a bandwidth greater than 500 MHz [1] [2]. While UWB has been a known technology since the end of the 19th century, restrictions on transmission to prevent interference with narrow-band, continuous wave signals have limited its applications to defense and relatively few specially licensed operators [1].
