A DARPA-funded team has drastically miniaturized highly specialized electronic components called circulators and for the first time integrated them into standard silicon-based circuitry. The feat ...

ALLEN, TEXAS—Fairview Microwave released new RF Circulators and Isolators, commonly used in radar systems, wireless communications, distributed antenna systems, test labs and amplifier systems where ...

A DARPA-funded research team said recently it had developed a tiny component for silicon-based circuitry that could double the radio-frequency (RF) capacity for wireless communications—offering faster ...

Pasternack's 3-port RF circulators (also referred to as RF duplexers) control the signal direction and flow inside of an RF circuit. RF circulators are unidirectional and circulate the flow of energy ...

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 ...

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 ...

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 ...
