The proposed capability enhancements from 4G long-term evolution (LTE) to 5G new radio (5G NR) were a massive leap designed to boost mobile telecommunications applications and enable many more. Aside from significantly boosting all major performance metrics, the 4G to 5G transition also heralds a more flexible and capable radio architecture with additional millimeter-wave frequency spectrum on top of legacy 4G LTE-Advanced (LTE-A) and new sub-6 GHz frequency bands.

With its small footprint, the R&S®ATS1000 antenna test system is the ideal direct far-field OTA system to test phased array antennas. The system tests and optimizes the radiation characteristics of any modules using the AiP technology from 18 GHz to 87 GHz. Register and learn more in our paper.

This document looks at how Feko—in conjunction with Altair’s solutions for design simulation, exploration and optimization, structural assessment, and thermal analysis—can help antenna designers develop and verify their antenna solutions quickly, accurately, and efficiently. It will focus on how to realize automated, iterative design optimization through modelling and visualization.

In millimeter wave designs, compression mount connectors can be used to avoid problems commonly associated with solder variations. However, when using compression mount connectors, the potential impact of pin compression and/or misalignment on electrical performance at high frequencies should be considered. Using modeled and measured data, this white paper investigates how misalignment and pin compression could impact a real-world design. It also explains how to detect and avoid issues in order to optimize performance and complete a successful design. 

Read this white paper to get an overview of the UWB standards and international UWB consortia, technical fundamentals of UWB technology and the high rate pulse (HRP) UWB physical (PHY) layer based on the IEEE 802.15.4 standard as well as the IEEE 802.15.4z standard.

There is more to selecting an inductor than the nominal inductance value. To ensure your choice will perform in your application, you need to give careful consideration to inductance tolerance, current ratings, DCR, operating temperature and efficiency under specific conditions. This paper provides students and anyone new to inductors with an overview of the key performance ratings they will need to understand when specifying RF and Power Inductors.

SHEERGARD® optimizes 5G radomes by being band agnostic; no tuning required and multiple antennas concealed in a single radome. Lightweight material ensures limited structural support needed, with low transmission loss at wide scan angles. Finally, hydrophobicity provides long-term UV and weather resistance, reduces signal loss and prevents ice/ snow build-up.

The expansion of electronic and radio frequency technology into almost every aspect of daily life has greatly increased the importance of electromagnetic compatibility (EMC) testing. This educational note discusses the fundamentals of EMC precompliance testing: what precompliance is, why precompliance is important, and how precompliance testing is performed.

According to Ericsson’s 2022 Mobility Report, global mobile data traffic is expected to grow by a factor of 4 to 325 Exabytes total per month or 46 GB per smartphone on average by 2028, excluding Fixed Wireless Access usage.

Phased array calibration efforts are generally focused on optimizing the fundamental signal of interest. This article presents a method to further improve spurious performance once the phase calibration for the desired signal is known. Using this method, we will evaluate transmit spurious signals on a 32-element hybrid beamforming system comprised of four 8-element subarrays.
