From military to commercial applications, engineers are always looking to extend the ranges of their current communications systems, whether that means in technical radios, datalinks on UAVs, or telemetry on a manned aircraft. Jarred Lawler from NuWaves at IMS 2018 presents a number of ways to extend range, including improvements in the antenna, MIMO capabilities, and power amplification.
C.J. Reddy from Altair talked to us today about efficient antenna design processes for wireless, wearable, and implantable devices using Altair FEKO simulation software. Check out the video for the advantages in using simulation software with as low computational electromagnetics (CEM) as possible when modeling devices to work well while in contact with the human body.
This afternoon at IMS 2018, Bror Peterson from Qorvo introduces the QPF4006 Front-End Module (FEM) for 5G millimeter-wave base stations. This is the only 39 GHz FEM that integrates an LNA, PA, and switch in one concise packaging. Watch the video for more information on the product, as well as a discussion of the product’s testing by Keysight Technologies.
Aerospace and defense markets are continuously trying to achieve more functionality in products with a smaller package size, and with multi-layer boards and RF performance beyond traditional X-bands. Art Aguayo of Rogers Corporation discusses the advantages for converging high-performance RF technologies with customary high speed digital technologies.
In this video at IMS 2018, Joe DiBiase discusses three approaches for improving EMC test lab efficiency. Check out the video for more on how test labs must accommodate all sizes of equipment and multi-test capabilities, the importance of speed, multi-purpose, and software capabilities in the utilized equipment, and using simple, flexible, and intuitive software for the best results in EMC test lab efficiency.
As greater efficiency becomes more critical in ground, mobile, and airborne applications, TWT technologies must meet these new requirements. At IMS 2018, Mike Lee from dB Control discussed with RF Globalnet SWaP advantages in radar, EW, and communications systems, as well as leveraging high efficiency innovations in TWTA and MPM designs.
Successful PA designs begin with accurate electrical simulations at the schematic level. When designing millimeter-wave MMICs, issues such as stability, electromagnetic coupling, and distributed effects are hard to address while maintaining design-rule check (DRC) integrity during the design process. This presentation addresses these important issues and describes some of the tools available to address them.
AR’s Design Supervisor, Elias Neno, provides a product demonstration on AR’s new Class A solid-state amplifiers designed for applications where instantaneous bandwidth, high gain and linearity are required.
AR’s “U” Series Amplifiers are designed with the broadest frequency ranges from 10 kHz to 1000 MHz, and offer a wide power spectrum from 1 – 25 Watts. Created with smaller, more affordable sizes without compromising on performance or durability, these amplifiers are ideal for multiple applications across diverse industries.
High peak-to-average power ratios (PAPRs) are not beneficial as they challenge the non-linear power amplifier operation close to compression in order to reach maximum efficiency. Possible solutions for include crest factor reductions (CFR), such as clipping high signal peaks. This video demonstrates a simple technique to clip any waveform, including the Verizon Wireless 5GTF signal, with the use of software tools for signal generation and analysis.
