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 ...

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 ...

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 ...

A team of researchers from Columbia University’s School of Engineering and Applied Science has developed a full-duplex radio integrated circuit (IC) that, it claims, can be implemented in nanoscale ...

An engineer has integrated a non-reciprocal circulator and a full-duplex radio on a nanoscale silicon chip for the first time. This breakthrough technology needs only one antenna, thus enabling an ...

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 ...

Anyone who has worked with high-power TV transmitters using IOTs or two-way radio repeaters using the same antenna for transmit and receive know conventional circulators are large and heavy due to the ...

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 ...
