07.25.23 -- Is It Too Late For mmWave To Save 5G?

The R&S ZNA vector network analyzer with integrated LO output and direct IF input options is a simple, cost-effective solution for two-port and four-port measurements using Rohde & Schwarz mmWave converters.

There will always be emerging threats in the defense sector that require the innovation that millimeter wave technology offers. Here’s a helpful Q&A primer on millimeter wave products — including what specialized contract manufacturing and environmental testing can bring to the table.

Operating in mmWave bands requires adherence to tighter tolerances. Test methods and positioner design and selection must provide this precision, as well as accommodate more directional beamforming and a total-system approach.

To support the advancement of satellite communications networks, test solutions must advance in tandem to analyze and validate next-gen performance. In two compelling demonstrations, Wireless Telecom Group uses unique solutions to meet the testing needs of the satellite communications industry.

AR’s state-of-the-art multi-tone systems are designed to test RF radiated and conducted immunity faster than ever before. Both the MT2IEC10V3M and MT4IEC10V3M fully comply with IEC 61000-4-3:2020 Edition 4, allowing for multiple tone testing, reducing test time by up to 74%.

Planar filters are manufactured by creating flat 2D resonators with patterns of strip elements on a dielectric substrate. Depending on the filter topology, planar filters can offer a high quality factor (Q) and a reasonable approach to achieving performance in a small footprint. 

The technology in today’s world continues to move higher in frequency to solve problems and improve performance. It is these millimeter wave (mmWave) frequencies that offer hope in solving the toughest requirements in many industries such as communications and defense.

Ensuring 5G New Radio (NR) user equipment (UE) operability as it is commercialized requires a greater emphasis on over-the-air (OTA) testing.
