In the world of electronic components, there are many devices out there that do their job well and reliably, but are almost never heard of – even though they may be vital to equipment that plays a ...

Researchers in the US have given the humble RF circulator a makeover. Not only is their prototype smaller, lighter, cheaper <i>and</i> more efficient, it's also claimed to be easily adapted to ...

This article originally appeared in TV Technology. Anyone who has worked with high-power TV transmitters using IOTs or two-way radio repeaters using the same antenna for transmit and receive knows ...

Circulators and isolators are commonly used in RF work. You should know how they work and the appropriate applications for each. A circulator is a three-port device that has an interesting ...

A new radio design from the University of Texas may have found a way to transmit and receive data simultaneously, without the need for specialized software networks. Could this new technology ...

New York, NY--April 15, 2016--Last year, Columbia Engineering researchers were the first to invent a technology--full-duplex radio integrated circuits (ICs)--that can be implemented in nanoscale CMOS ...

Researchers at Columbia University in New York have created an rf circulator that works at 25GHz. It uses a non-reciprocal structure – one whose physical characteristics differ depending on the ...

Front-end limiter circuits using Schottky and PIN diodes can provide needed protection in communications and other RF systems. However, designers still must deal with the upper-frequency limit problem ...
