Signals in the mmWave range require extra care and more expensive components than at sub-6 GHz frequencies.
Front-end mmWave IC combines PA, LNA, and switch
mmTron announced its first single-chip front-end IC for mmWave communications. Covering 24 to 30 GHz, the TMC252 integrates a power amplifier (PA), low noise amplifier (LNA), and transmit-receive switch on a single GaN IC that is available as a die or packaged in a 5 mm x 5 mm air-cavity QFN. The TMC252 is well-suited…
Build a 5G Open RAN test lab with open-source software tools
Open-source software provides network components that you can use to simulate 5G network functions from the network core to the radio. Developing and deploying a laboratory infrastructure to support testing 5G and open radio-access network (Open RAN) systems can present a daunting and complex task. Prior to Open RAN, this task was only possible by…
Dual-band positioning IC boosts accuracy in urban areas
u-blox has announced F10, the company’s first dual-band GNSS (Global Navigation Satellite Systems) platform combining L1 and L5 bands to offer enhanced multipath resistance and meter-level positioning accuracy. The platform caters to urban mobility applications, such as aftermarket telematics and micromobility. Applications that use GNSS receivers for accurate positioning are on the rise. Yet, current…
Flexible PTP profiles ease the transition to 5G
5G brought architecture changes that require synchronization. Depending on the location and network site, those timing requirements require different PTP profiles and PTP capacity.
Researchers develop frequency-selective surfaces
The growing number of devices connected to wireless networks has highlighted the need for innovative solutions to ensure seamless connections. Now, researchers from Nagoya Institute of Technology have introduced a metasurface that can distinguish wireless signals based on both frequency and pulse width. This metasurface can be integrated into antennas to accommodate more devices within…
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.
Cellular SoC includes RF amp, power management, GNSS, NB-IoT, and DECT NR+
Nordic Semiconductor announces the expansion of its nRF91 Series cellular IoT devices with the introduction of the nRF9151 System-in-Package (SiP). The nRF9151 further enhances Nordic’s end-to-end cellular IoT solution, which encompasses hardware, software, tools, and nRF Cloud Services, providing advanced capabilities and seamless integration to significantly simplify the development process. The nRF9151 offers a compact,…
6G could add sensing to cellular networks
Integrated communications and sensing at mmWave and sub-THz frequencies could add location detection that helps avoid accidents among pedestrians, bicycles, and vehicles.
Wireless tester performs Wi-Fi 7 PHY and MAC layer tests
Keysight’s E7515W lets you test Wi-Fi 7 chipsets and systems. As Wi-Fi 7 (802.11be) chipsets, routers, access points, and mobile devices come into production, engineers need to test them for RF conformance and for protocol functionality. Keysight automates those tasks by adding Wi-Fi 7 testing with the E7515W. A variant on its UXM test platform,…
