By going contrary to conventional thinking, a design team devised a more efficient regulator device for the DC-power path. DC regulators are available in many different topologies, each offering tradeoffs in performance, size, efficiency, cost, and other factors. Regardless of their internal design, they all have one primary functional role: to accept a DC voltage […]

IEEE Phased Array 2024: what we saw
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…
IMS 2024 roundup: RF components
Washington, DC — The International Microwave Symposium (IMS), which took place here in June 2024, featured a wide array of RF, microwave, and mmWave components. These components range from passive connectors and waveguides to amplifiers, switches, filters, and data converters. In general, these components make their way into military communications systems or commercial wireless networks.…
APEC 2024: Semiconductors, modules, transformers, and chargers
Power supplies from phone chargers to EVs to industrial machinery rely on semiconductors, either in discrete packages or integrated into power modules, to deliver power. APEC 2024 was full of power sources and components. The roundup below highlights regulators, switches, and power semiconductors. We also highlight wireless power delivery and chargers. Be sure to see […]
6G conference exhibits demonstrate possible technologies
At the 6G Symposium and 6G Summit, attendees saw the latest research that could lead to the next generation of wireless.
IMS 2023 roundup: semiconductors and microwave components
Through photos and videos, EE World covers some of the active and passive components that RF and wireless engineers need to connect us all. The exhibit hall at the 2023 International Microwave Symposium in San Diego consisted of 560 exhibitors, too many for this editor to visit in three days. For 2023, we improved our…
SoC generates RF test signals and analyzes results
The Apollo MxFE software-defined signal processing SoC from Analog Devices digitizes and generates analog signals with DSP in between. Applications cover aerospace & defense, instrumentation, and wireless communications. Digitizing high-speed signals, processing them, and creating responses typically requires separate ADCs, DACs, and DSPs or FPGAs. The Apollo MxFE system-on-chip (SoC) combines signal capture, creation, and […]
5G mmWave signal chain: the phase-locked loop
In “Look inside the 5G mmWave signal chain,” we explored the overall architecture of the mmWave signal chain. Now, we’ll look deeper into each of a transceiver’s components. Phase-locked Loops (PLL) are important blocks for a clean reference clock generation in cellular networks. In 5G mmWave radio networks, the PLL supports data rates of 1…
Power windows: now much more than just a motor and switch, Part 2
The automotive power window has evolved from a basic on/off switch and motor to a sophisticated motion-control subsystem with dedicated ICs. As with most improvements, there are both expected and unanticipated ripple effects in product objectives, associated design, and actual production. As cars became increasingly “electrified” with more motors, switches, lighting, power seats, infotainment, advanced […]
Reference design platform cuts 4G/5G radio design time
The ADRV904x-RD reference design from Analog Devices includes an 8T/8R transceiver and covers from RF to optical.
