This passive device lets you steer signal beams for over-the-air wireless test systems. Vaunix Technology, a manufacturer of modular RF/wireless test equipment, has introduced the LBM-7250-4 Lab Brick Butler Matrix, a beamforming tool that works with phased-array antennas to steer beams between transmitters and receivers. The Butler Matrix has four passive inputs and four outputs…

This passive beamforming topology is not well known but is widely used — a common situation in the RF world. For many years, radar applications defined much of the world of directional antennas. These antennas were designed with a fixed directivity or rotated in a steady pattern at a known rate, as seen in Figure…

The IEEE Phased Array conference occurred in Boston on October 15-17, 2024. This specialized conference had a small exhibit floor. Here is some of what was on display. Boston — The 2024 IEEE International Symposium on Phased Array Systems & Technology moved into the city after taking place in a suburban Boston hotel for several…

In a video interview, Harrison Osbourn explains that he handle the CEO-level functions while Tom Lane takes over as president.

At the May 2022 6G Symposium, three speakers proposed modulation and coding methods for 6G. As you might expect, they keep getting more complex to handle the expected higher data rates.

As the tugboat Nellie Bly circumnavigated Denmark, engineers and a remote crew kept an eye on the vessel from a control room in Boston. A 4G connection provided the internet connectivity. These videos bring you into the control room. Autonomous sea vessels show promise as the next step in water navigation. Of course, such vessels…

The BGT60LTR11AIP from Infineon Technologies lets you add a 60-GHz motion sensor to embedded devices.

At the 2021 (virtual) IEEE Microwave Symposium, the industry looked at where wireless is going and how it will get beyond 5G.

Keysight’s N9042B UXA X-Series signal analyzer lets you analyze mmWave and sub-6 GHz signals while keeping the noise down.

The SMM100A series of vector signal generators from Rohde & Schwarz have models that generate RF signals from 100 kHz with a high-end model to 44 GHz. That covers today’s 5G frequencies and more.
