Standard filters reflect unwanted stopband energy, but reflectionless filters present a seamless impedance across both stopband and passband which greatly improves performance of the RF signal chain. Filters are an area of intense interest, analysis, simulation, and often physical fabrication along with tests and academic papers. Yet, for hands-on design engineers, it’s important to be […]

What are reflectionless filters, Part 3: Basic principles
Standard filters reflect unwanted stopband energy, but reflectionless filters present a seamless impedance across both stopband and passband, which greatly improves performance of the RF signal chain. Beginning in 2011, Dr. Matthew A. Morgan of the National Radio Astronomy Observatory (NRAO) in Charlottesville, West Virginia, working with Tod A. Boyd and later with Wavley M. […]
Dual-channel low-side 4/5-A gate driver ICs handle fast MOSFET, WBG switches
Infineon Technologies AG has released the new EiceDRIVER 2EDN product family. Aiming at space-limited designs, the next-generation devices complement the existing 2EDN driver ICs by providing higher system-level efficiencies, excellent power density, and consistent system robustness with fewer external components. Building upon this expansion, the 2EDN family is now able to drive the power switch […]

The new power supplies are well-suited for industrial applications including outdoor digital LED signage, traffic light equipment, industrial […]
What are reflectionless filters? Part 1: Context
Standard filters reflect unwanted stopband energy, but reflectionless filters present a seamless impedance across both stopband and passband which greatly improves performance of the RF signal chain. Filters are an inherent, inescapable, necessary component in electrical and electronic circuits. Modern systems would be impractical and likely impossible without filters, whether at low frequencies down to […]
Satellite-based search-and-rescue, Part 4: Enhancements, even the moon
A sophisticated satellite-based system allows pinpointing a person’s location in a dangerous, isolated situation on land or sea. It thus hopefully speeds their subsequent rescue in many cases. This final part looks at the next generation of system satellites and some ideas for a similar lunar system. The MEOSAR satellites The most recent enhancement to […]
Ka-band phased-array satellite antenna meets CS25 and CS27 needs
ThinKom Solutions, Inc. unveiled a new Ka-band phased-array satellite antenna for communications-on-the-move (COTM) applications. The new ThinSat Ka500, based on ThinKom’s proven VICTS technology, is a “turnkey” terminal that enables the user to easily and quickly connect to the network of their choice, such as the existing and new Ka-band networks being deployed using satellites in geostationary […]
