Research at the Department of Medical Biophysics at the Sunnybrook Research Institute (SRI) aims to develop and demonstrate the application of new technologies for brain imaging. A recent project focused on developing ways to try and safely image patients with Deep Brain Stimulation (DBS), and reducing the heat created during an MRI as a result implant interaction with RF transmission fields. This case study details how FEKO® simulation software was used to create the electrical and magnetic fields required for imaging in an MRI environment.
The increased awareness around passive intermodulation (PIM) comes with the growing complexity of how spectrum is utilized. This white paper offers a brief introduction to PIM, and considerations for designing a system with PIM in mind.
There are many challenges associated with improving the Size, Weight, and Power (SWaP) of electronic devices, including the limitation of the physical size and assembly processes, and spectrum congestion forcing new systems to move to higher frequencies. This article addresses these issues by discussing when to use a custom MMIC in the design process.
When developing a communication datalink range, it is important to consider the ability to provide sufficient signal strength out to the intended operational range of the platform. This article discusses the options available to improve the datalink range for different applications.
Unmanned aerial systems (UAVs) are continually advancing in respect to both defense and domestic applications. The fast development pace has led to an expanding list of missions that increase the demand on systems in terms of power consumption, payload, and the ability to operate beyond line of sight safely and reliably. This article discusses the importance of Size, Weight and Power (SWaP) to missions with UAVs.
EMI Filters are used to prevent electromagnetic interference in avionics and aircraft systems, as well as military shipboard/vehicle electronics, and in military communication systems. Electromagnetic interference can cause a complete loss of data in communications systems, or a simple decline in data quality.
The Fischer Plastic Series is a family of high performance, fully insulated plastic connector bodies that are all compatible with Fischer’s metallic connectors. Key features include high reliable signal path, high signal and contact density, clear coding for easy operation, and resistance to large temperature variations.
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.
