Samtec, Inc. has announced the release of its NovaRay cable assemblies. These assemblies use 40% less space compared to traditional arrays, supporting 112 Gbps PAM4 per channel. They are suitable for applications in datacom, AI/ML, HPC, computer and semiconductor, medical, test and measurement, military/aerospace, and mobile networks. Samtec’s NovaRay cable assemblies provide low crosstalk (<30…
Wi-Fi performance testing now has standards
By Leigh Chinitz, Spirent Communications Until recently, service providers were unable to predict in-home performance of Wi-Fi devices because they lacked standardized test cases. Now, industry groups have advanced three new standards, each geared toward different Wi-Fi use cases. The Wi-Fi industry has long had standardized conformance testing to confirm that a device meets standards…
How to reduce residual noise in 5G NR EVM measurements
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.
Our 2024 Communications Handbook is here
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…
Optimize RF signal quality in 5G power amps
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)…
Four-port switch lets you connect antennas to radios and test equipment
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.…
How GaN PAs in 5G radios push test requirements
Proper PA development, validation, and characterization are important because a PA often accounts for a significant portion of a transmitting device’s power consumption.
RF power sensor covers 25 MHz to 1 GHz
Anritsu Company announces the launch of their new inline power sensor MA24103A which is designed to measure accurate Peak and True-RMS average power measurements from 25 MHz to 1 GHz and 2 mW to 150 W power range. Several applications demand accurate peak and average power measurements well below the frequency range of 1 GHz.…
OFC 2024: It’s AI or die
Today’s data rates are already too slow, and so are tomorrow’s. Expect more complaints about slow networks in 2025.
Small footprint 3GPP 5G conformance test systems perform RF and radio-resource tests
Rohde & Schwarz has developed two additions for its R&S TS8980 family: the R&S TS8980S-4A and the R&S TS8980FTA-3A.
