The new RF circulator uses a circuit created from inexpensive, surface-mount, active semiconductor components. The team predicts that the current prototype is just a start to the miniaturization; ...

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 ...

What's more, because the design of the circulator is scalable and capable of circuit integration, it can potentially be placed in wireless devices. "We envision micron-sized circulators embedded in ...

The circuit (see top photo) is built on a 45nm SOI CMOS process. Circulators “The key advance of this new approach is that it enables circulators to be built in conventional semiconductor chips and ...

Practical Use: Circulators and Isolators Apr 1, 2014 8:35 AM, By Doug Irwin, CPBE DRB AMD Circulators and isolators are commonly used in RF work. You should know how they work and the appropriate ...

A circulator is a device that's used to transmit a radio signal through a series of ports and to ensure that signals transmitted through one port only exit through a second port -- Port 1 always ...

Unlike magnetic circulators, this design can operate over a wide range of frequencies. Nicholas Estep, lead researcher and a doctoral student in the Department of Electrical and Computer Engineering ...

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 ...
