The power divider stands out from those in the literature, by both simple design procedure and layout. The design procedure using the derived equations is demonstrated with two proof-of-concept prototypes, fabricated on a 20-mil-thick RO4003C substrate. 原文传递 原文传递并翻译 示...
In the realm of accidental inventions, the matchstick stands as a testament to serendipity's role in scientific advancement. It was in 1826 when English chemist John Walker stumbled upon the idea for the modern match. While working in his laboratory, Walker accidentally scraped a mixture-coated ...
This section introduces the proposed framework for multi-criterial tuning of microwave circuits with explicit handling of fabrication tolerances. We aim at identifying a set of designs ensuring trade-off between robustness versus nominal performance of the circuit. Towards this end, “MO with tolerance...
TBHQ that is found in Smart Balance, stands for “Tertiary Butylhydroquinone.” It’s a dead giveaway that you shouldn’t be eating this, if food companies have to use an acronym for a long chemical name on the ingredient label.TBHQ is a chemical made from butane (a very toxic gas) ...
The main source of phase shift (and therefore what mostly determines the oscillator frequency) in the feedback path is the SAW filter, in the gold can. SAW stands for"Surface Acoustic Wave" (SAW); it's essentially a mechanical delay line but which can propagate even multi-Ghz ...
stands for Wi-Fi, Wi-Fi 6E, 4G, 5G, LTE, DVB, microwave radio fading simulators and for engineering/production test labs. Also announced was the the new BLX-403 Lab BrickTMportable and programmable signal generator for RF and microwave test and measurement applications up to 40 GHz. This ...
This 30 pF multiturn trimmer capacitor uses a patented solid polytetrafluoroethylene dielectric design to withstand 5000 V DC and cannot short out. The unit offers 10 turns of linear tuning and Q is > 2000 at 100 MHz. The O-ring seal withstands 40 psi. Panel-mount, stripline, vertical or...
One single study, however, does point to a relatively strong air pollution risk —it stands out like Gulliver among the Lilliputians when placed next to other similar efforts. This one study is by two other amateur epidemiologists, who had years of support from EPRI. ...
The model PC806N directional yagi antenna receives and transmits in the 806 to 866 MHz frequency band. The completely waterproof construction is achieved by enclosing the feed system in a potted polyvinyl chloride radome. The pigtail feed withstands a 50 lb pull, ensuring reliability. Adjustments...
The authors synthesized Au nanoparticles with a size of 1–2 nm by microwave-assisted decomposition/reduction of Au(CO)Cl or KAuCl4 in the ionic liquids [BMIm]+[BF4]−, [BMIm]+[OTf]−, [BtMA]+[NTf2]− (where [BMIm]+ stands for n-butylmethylimidazolium cation, [BtMA]+ is n...
