Error vector magnitude (EVM) is the most important figure of merit for signal quality in 5G NR. A new method improves measurement accuracy by reducing noise.

The infrastructure of data communications networks needs lots of fiber, semiconductors, and network equipment to bring data to the masses. Optical data networks form the backbone of today’s communications. Data centers, which seem to dominate any discussion of digital communications, depend heavily on fiber-optic connections from a few meters to many kilometers. Getting those bits…

EE World announces its 2024 5G, Wireless, & Wireline Communications Handbook in digital form. It’s that time again. EE World’s 2024 5G, Wireless, & Wireline Communications Handbook is here. The 41-page e-book contains ten technical articles plus an editorial. This year, we cover: Network timing, mmWaves (two articles), Power amplifiers (three articles), test & measurement…

The ART2K5TFUS and ART2K5TFUG power transistors from Ampleon amplify signals from 1 MHz to 400 MHz.

It’s not always easy for an engineer to determine the best networking and fiber optic measurement solution to address their measurement needs. To help with that, this webinar discusses: The what, why, and how of available options like optical spectrum analyzers, optical wavelength meters, optical power meters, variable attenuators, fixed and tunable laser sources, and…

For 5G system performance, obtaining and maintaining the right balance of requirements for high power, power-added efficiency, and signal fidelity is critical. CCDF and PAPR measurements provide insights to help power amplifier designers achieve that goal. While all parts of the 5G RF signal chain contribute to overall system performance, the transmitter power amplifier (PA)…

Signal Hound announced the addition of the RFS44 to its expanding product line. This powerful, ultra-fast antenna switch is in stock and available to Order Now. The RFS44 is a single pole four-throw (SP4T) absorptive solid state switch. Using silicon-on-insulator (SOI) technology, the RFS44 provides RF switching across four ports at up to 44 GHz.…

When designing wireless connectivity into IoT devices, you have several options for antennas. You can design one right into a PCB, but several commercial options take the work out of designing your own.

As 5G-Advanced evolves and transitions to 6G, standards and pre-standards bodies have begun to align on the new features and enhanced capabilities that will define the next generation of wireless. A new report commissioned by InterDigital, Inc. introduces the enhancements to 5G capabilities and the novel features of integrated sensing and communication, native AI, and…

Proper PA development, validation, and characterization are important because a PA often accounts for a significant portion of a transmitting device’s power consumption.
