Huawei pleads its case in the U.S., Verizon targets competitors' broadband dominance, Seattle takes the fight to the FCC, and spectrum auction costs continue to spiral out of control, all in this edition of The Week In 5G.
The promise of wearables, functional fabrics, the Internet of Things, and their “next-generation” technological cohort seems tantalizingly within reach. But researchers in the field will tell you a prime reason for their delayed “arrival” is the problem of seamlessly integrating connection technology — namely, antennas — with shape-shifting and flexible “things.”
Verizon's four-city 5G rollout in the U.S. has begun, the FCC passed rules to stifle local governments' authority regarding infrastructure placement and fees, spectrum auctions in the EU are pricier than expected, and Huawei scores wins in Russian and Monaco, all in this edition of The Week in 5G!
Role Call is a series on RF Globalnet that will explore each of these topics with a “peek behind the curtain” at different jobs and career paths in the RF and microwave industry. Our most recent subject is Trushal Vijaykumar Chokshi, the Principal Systems Design Engineer at SiTime. Trushal specializes in the development of high-throughput systems for micro-electro mechanical systems (MEMS) resonators and oscillators, relying on a background in physics and electrical engineering with a focus on MEMS and analog circuits.
The behavior of transmission lines in RF systems becomes important when the transmitted frequency’s wavelength is short enough that the length of cable becomes a significant part of a wavelength. Microstrip consists of a conducting strip separated from a ground plane by a dielectric substrate.

This wide range of connector types may be used in many different markets including phased array radar, electronic warfare, military, and communication systems.
Skyworks offer two new front-end modules (FEMs) for GNSS/GPS/GLONASS/Galileo/Compass/QZSS radio receiver applications in the 1559 to 1606 MHz frequency range. The SKY65933-11 and the SKY65943-11 feature an integrated low noise amplifier (LNA), and a pre-filter and post-filter. Both devices use surface-mount technology (SMT) in the form of a 2.5 x 2.5 mm Multi-Chip Module (MCM) package, which allows for a highly manufacturable and low-cost solution.
Skyworks’ newest family of compact, high performance RF front-end modules (FEMs) is specifically designed for LPWAN – supporting LoRa®, SigFox and other unlicensed band technologies – as well as high-power Industrial, Scientific, Medical (ISM) applications operating in the 860-930 MHz frequency range. These new solutions deliver improved sensitivity and more than quadruple the operating range versus a standalone system-on-chip (SoC).

Measure frequency vs. time using the new Transient Mode measurement option on the Berkeley Nucleonics Phase Noise Tester. This measurement mode enables both wide band and narrow band measurements with high measurement rates and long measurement spans (track drift over time). Use the wide band measurement to analyze large frequency changes. Measure and characterize a 100 uS transient period between a 1 GHz and 2 GHz signal from an RF Signal Generator. Measure and characterize a 10 kHz frequency modulation.
This video provides a short tutorial on measuring ultra-low phase noise on a 100MHz OCXO using tunable external references. Measure over a wide range, 1Hz to 50MHz offset, using just 2 cross correlations. You can also measure -182 dBc at 1MHz, -177dBC at 10kHz, and -162 dBc at 1kHz.

Antennas need to cope with some of the world’s harshest and most isolated ocean environments. Intense cold, extreme corrosion, ice, rain, hail, vibration and the constant jarring force of the waves must all be overcome on a daily basis.
A new study shows that terahertz data links, which may play a role in ultra-high-speed wireless data networks of the future, aren’t as immune to eavesdropping as many researchers have assumed. The research, published in the journal Nature, shows that it is possible for a clever eavesdropper to intercept a signal from a terahertz transmitter without the intrusion being detected at the receiver.
