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; ...

NXP’s packaging results in an RF PA module which is thinner and lighter than existing designs, with a better thermal path as well. This top-side cooling contrasts with conventional bottom-side cooling ...

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 ...

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 ...

The QPF5001 can interface with a circulator. Its transmit power is 12 W saturated and the receiver noise figure is 1.5 dB. The QPM2101 S-band VGA is designed for S-Band radar applications in the 2 ...

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 ...

If you need an amplifier, [Hans Rosenberg] has some advice. Don’t design your own; grab cheap and tiny RF amplifier modules and put them on a PCB that fits your needs. These are the grandchil… ...

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 ...

"Our circulator is the first to be put on a silicon chip, and we get literally orders of magnitude better performance than prior work. Full-duplex communications, where the transmitter and the ...
