Millimeter-Wave Beamforming Overview & Design Choices

by Rohde & Schwarz Current cellular 4G networks face a multitude of challenges. Soaring demand for mobile high-resolution multimedia applications brings these networks ever closer to their practical limits. 5G networks are envisioned to ease the burden on the current infrastructure by offering significantly higher data rates through increased channel bandwidths. Considering the shortage of […]

The Metamorphosis of the Wireless Network Testing Market

by Olga Yashkova, Program Manager, Measurement & Instrumentation Practice, Frost & Sullivan Most of us are quite aware of rapidly increasing mobile data traffic. According to Cisco, global mobile data traffic grew 63 percent in 2016. Smartphone users spend nearly 80 percent of their daily device use time on non-voice activities. Traditional capacity expansion is not […]

The Impact of the IoT Demystified

by Cees Links, GM of Qorvo Wireless Connectivity Business Unit The IoT (Internet of Things) is a modern-day buzzword with lofty expectations to have a profound impact on society. But what is it, how will we use it and what will that impact be? Is it exciting or will it be frightening? Will it be […]

An RF Simulator for Enhanced Cascade System Analysis

by Dale D. Henkes, ACS Equation 1:  P1dB = 10*Log[(1/(P1dB_1*G2*G3) + 1/(P1dB_2*G3) + 1/(P1dB_3))^(-1)] In the design, development and production readiness qualification of RF products, the modern trend is tending to more collaboration between the “high level” systems people and the detailed circuit design engineer. Responsible for flowing down the product specifications to sub-system and […]

Design and Matching of a 60 GHz Printed Antenna using NI AWR Software and AWR Connected for Optenni

by Jaakko Juntunen, Optenni Ltd (all images are at the end of the article) Impedance matching of high-frequency components is an important step in any antenna design to ensure maximum transfer of power between the antenna and the transmitter/receiver circuitry. By first designing a matching circuit, antennas can be tuned to resonate at the desired […]

Overcoming C-band Satellite Interference

by Douglas Chun, Norsat International C-band on the Rise Satellite services are being severely disrupted by interference from new Broadband Wireless Access (BWA) networks operating in the C-band frequencies from 3.4-4.2 GHz. Traditionally, this range of C-band is used for satellite services, radar, and microwave links; however, with the terrestrial wireless industry’s planned introduction of […]

Commercial and Military Innovation at a Crossroads for Radar and Wireless Networking Applications

by Tony Fischetti, Principal Technology Architect, MACOM From the modern battlefield to commercial wireless infrastructure, bandwidth demands are growing exponentially. In the aerospace and defense (A&D) market, these demands are being driven by the need for low-latency communication and enhanced situational awareness and responsiveness among warfighters deployed across ground, sea and air domains, serviced by […]
