Can dielectric waveguide antennas boost 5G efficiency?

Aharon Etengoff — Wed, 29 May 2024 16:05:28 +0000

5G base stations rely on phased arrays to steer signals and increase data rates. Beam steering circuits, however, consume power. Using waveguides could reduce energy consumption in base stations. Waveguides are physical structures that direct electromagnetic waves from one point to another, confining energy within specific boundaries to control propagation, direction, and mode. While waveguide…

5G is much more than cell phones. IoT devices, medical devices, and industrial devices can connect to networks using technologies such as TDD, network slicing, and beamforming. 5G New Radio (NR) made its long-awaited commercial debut in late 2018. Offering significantly faster speeds and greater capacity compared to 4G Long Term Evolution (LTE), 5G NR…

Front-end mmWave IC combines PA, LNA, and switch

Redding Traiger — Thu, 21 Mar 2024 18:38:15 +0000

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…

Report models performance of reconfigurable intelligent surfaces

Redding Traiger — Sat, 22 Jul 2023 18:25:45 +0000

ETSI unveils a new Report developed by its Reconfigurable Intelligent Surfaces group. ETSI GR RIS-003 explores communication models that offer a trade-off between electromagnetic accuracy and simplicity for performance evaluation and optimization. It also analyses channel models that include path-loss and multipath propagation effects, as well as the impact of interference. The last part of…

5G mmWave signal chain: the phase-locked loop

Steve Taranovich — Fri, 12 May 2023 04:07:23 +0000

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…
