Spotlight On Wireless Infrastructure
Why GaN Is 5G’s Super ‘Power’: A Series

While some feel GaN is still a relatively new technology, many can't dispute how it's advanced to the head of the class. Gallium nitride is a technology on the cusp of dethroning silicon LDMOS, which has been the material of choice in high power applications. 

EM Simulation Of Dual-Band And Wideband Dual-Polarized Cylindrical Dielectric Resonator Antennas For WLAN

Dielectric resonator antennas have numerous characteristics that make them useful, including low loss, high efficiency, and compact size. This example demonstrates how XFdtd analyzes two similar cylindrical dielectric resonator antennas (DRA), developed for dual-polarization performance for different bands.

A Classic LNA Design Challenge: Meeting The Satellite Digital Audio Radio Service (SDARS) LNA Specification

This article focuses on a high-volume application: the multi-stage LNA associated with the SDARS radio capability included with millions of new cars every year. It requires a cascade of multiple high-performance amplifiers and filters to meet a very difficult set of requirements.

5G New Radio Over-The-Air Base Station Receiver Tests

This application note describes all mandatory RF receiver tests, according to the Release 16 (V16.3.0). It also offers a brief introduction about the different R&S OA antenna test solutions and how they are applicable for base station conformance testing.

Who’s Looking Out For Your Spectrum?

As the number of participants in communication systems increases, so does the noise level. To be heard, you either increase your volume, request them to repeat themselves, or wait for a quiet period.  These basic principles form the building blocks of the wireless world we find ourselves in.

5G Fixed Wireless Access

Fixed wireless access (FWA) is one of the early planned use cases for 5G deployment, offering a new wireless alternative for providing broadband to homes and businesses. Because this requires very high bandwidth, many solutions for FWA consider use of new millimeter wave bands. This poses challenges for coverage, including increased path loss, weaker penetration through walls into the interiors of structures, and greater effects from shadowing of structures and trees on the outdoor propagation.
