Quectel Wireless Solutions announces that its 5G New Radio (NR) modules series, the RG620T has received FCC/ IC/ CE and RCM certifications. The RG620T series is the first 5G module based on the MediaTek T830 System-on-Chip (SoC) to receive all these certifications. The certifications will enable customers to efficiently deploy their 5G fixed wireless access (FWA)…
FAQ: Antenna-in-package answers the “last mile” RF challenge, Part 1
If you think antennas must live “outside” a circuit, think again: they can also be housed in a small package adjacent to the active components they serve. The RF signal chain has become increasingly integrated in the past years. Whether by merging RF circuitry with the digital function onto a single die or by co-locating…
EE World’s 2023 communications handbook is here
Our 2023 5G, Wired, & Wireless Handbook is now available in ebook form. Download your copy today. It started on a cold January day with an editorial call. A month later, the abstracts came in. After another month, the manuscripts came in. Then came the editing and some back-and-forth with the authors. Next, it was…
5G mmWave test builds on RF best practices
The high level of integration in today’s mmWave phone means traditional test methods no longer apply.
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…
Identify, troubleshoot, and resolve PIM issues in wireless networks
5G brought passive intermodulation problems into the spotlight. Now it’s up to engineers and technicians to identify and mitigate signal degradation to minimize dropped calls and other issues. A loose connection; a metal roof; power lines. Even a rusty bolt. It’s estimated that mobile operators will spend $1.1 trillion on capital expenditure between 2020 and…
Test methods for mmWave AiP designs bring tradeoffs
Engineers have several mmWave over-the-air test methods available for evaluating phased-array antennas used in antenna-in-package designs. Each has pros and cons.
Look inside the 5G mmWave signal chain
Millimeter wave signals provide wider bandwidths and higher data rates than signals at lower frequencies. Take a look at the overall signal chain that falls between the antenna and the digital baseband. 5G new radio (5G NR) adds mmWave frequencies to cellular devices and networks. With that comes RF-to-baseband signal chains and components not needed…
LITEON unveils 5G and beyond private network RAN solutions at MWC 2023
At MWC Barcelona 2023, LITEON Technology is showcasing 5G private solutions for different use cases. It provides the operator and system integrator with the capabilities to deliver more accurate coverage and better overall connectivity by overcoming the challenges associated with scarce spectrum in the country’s dense areas. For more composite and diverse 5G private networks…
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.
