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. […]

RF test module extends range to cover 6 GHz band
Anritsu adds 5G SA to its radio test set
Ultra-low profile dc-dc converters power 12-A loads
TDK Corporation announces the availability of the FS1412 microPOL (μPOL) power module. At 5.8. mm, x 4.9 mm x 1.6 mm, the FS1412 is part of a new series of µPOL DC-DC converters with increased performance, smallest available size, ease of use, and simplified integration for applications such as big data, machine learning, artificial intelligence […]
What are reflectionless filters? Part 2: The need
Standard filters reflect unwanted stop-band energy, but reflectionless filters present a seamless impedance across both stop band and pass band which greatly improves performance of the RF signal chain. The higher frequency world of hundreds of megahertz and into gigahertz is very different than the low-frequency world. It is a world where design tools […]
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 […]
