WITH A MULTITUDE OF WARFIGHTERS in what seems to be a never-ending array of locations, making sure they stay in contact has become more difficult than ever. Often, this situation is further challenged by rough terrain, which blocks line-of-sight ...
From wireless communications through test and defense applications, filters are balancing tradeoffs to shrink size, increase ruggedization, or provide flexibility without hurting performance.
By carefully selecting the parameters of a rectangular groove in a multi-mode resonator, the passband performance of an UWB bandpass filter can be enhanced.
This novel transmission-line technology provides compact three-dimensional structures with low loss compared to microstrip and stripline, and with impressive tolerance to high vibration levels.
The use of DGS units and stepped microstrip lines with standard low-loss microwave substrates can lead to miniature lowpass filters with extremely wide stopband ranges and excellent return-loss performance.
This extraction method shows how to design a microstrip high-low lowpass filter by combining an arrowhead-shaped defected ground structure with multilayer circuit fabrication techniques.
This broadband but compact amplifier features high efficiency with 100 W output power from 500 to 2500 MHz for applications in laboratory testing, as well as in electronic-warfare systems.
An increasing number of services and applications are relying on space-based technology. Examples include navigation, satellite broadcasting, and even medical research. Yet such services could be easily interrupted by collisions with space debris...
