Cambridge, Mass. — On a cold, wet, windy day about two weeks after baseball season opened, the 2023 Swapfest: The Flea at MIT season opened. Ocurring on the third Sunday morning of the month through October, the swapfest isn’t so much for swapping, but more for buying and selling. While I didn’t buy anything on […]
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…
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…
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.
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.
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.
RF driver powers four high-power amplifiers to 1.7 kW
Mini-Circuits driver amplifier and high-power amplifier combine to deliver 1.7 kW at 27 MHz.
How timing propagates in a 5G network
5G’s high speeds place extreme demands on the components that maintain accurate time. Compliance with industry timing standards calls for accuracy in the face of temperature changes, shock, and vibration.
Module brings Wi-Fi, Bluetooth, Thread, and Matter to embedded designs
The IRIS-W1 module from u-blox lets IoT devices connect over Wi-Fi an Bluetooth while supporting Thread and Matter protocols.
Functional tester covers bench, production, and service applications
The midUTS from Bloomy contains a multimeter, data-acquisition, switching, and power supplies for testing boards and systems. Automating tests — whether for bench testing new designs, in production, or for service — increases productivity but comes at a price. If you’re going to build an automated test system all yourself, expect to specify the instrumentation, […]
