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…
LoRaWAN modules connect IoT devices to 15 km
The RM126x series from Laird Connectivity integrate a processor and radio that connect IoT devices for data transfer.
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.
Voltage and TTL-controlled attenuators reduce RF signal power
Pasternack has launched a new line of voltage-controlled analog attenuators and TTL programmable attenuators. These new models offer comprehensive frequency coverage from 1 MHz to 50 GHz and are designed to provide precise and reliable signal attenuation for a variety of applications. Pasternack’s new voltage-controlled analog attenuators offer a broad attenuation range of up to…
Analyze signal integrity in serial links with pyBERT
EE World spoke with David Banas, who demonstrated pyBERT, the free and open software for signal-integrity analysis where he explains the motivation for its creation.
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…
How does PAPR reduction improve power amplifier efficiency?
5G’s Orthogonal Frequency Division Multiplexing (OFDM) brings with it a major design challenge, namely an inherent wide dynamic variation between a signal’s peak and the average power. The peak-to-average power ratio (PAPR) leads to inefficient transmission performance. That’s because the OFDM waveform is created by the sum of multiple sinusoidal signals that can exhibit constructive…
Gain blocks target 4G/5G
Guerrilla RF, Inc. announces the production release of the GRF2010 and GRF2011, two high linearity gain blocks targeting infrastructure applications such as 5G/4G base stations, automotive telematics, and cellular repeaters/DAS. These new cores extend the gain coverage for GRF’s existing portfolio of general-purpose RF/microwave gain blocks. When used in conjunction with the popular GRF2013, customers can now choose from a…
Analyzer software automates radar test
Anritsu Company introduces the Pulse Radar Measurement Function MX284059B software for its Signal Analyzer MS2840A that creates a single-instrument solution for automated pulse radar measurements to dramatically reduce cost-of-test and test time on the production line and in the field. The MS2840A, when equipped with the new software and the USB Peak Power Sensor MA24406A/18A/40A, supports tests of…
