Metal-clad Fibers with Significant Weight Savings and EMI Performance

Micro-Coax, Pottstown, PA

Micro-Coax is now offering the ARACON“ family of metal-clad fibers that combines the conductivity of metal with the strength, light weight and flexibility of Kevlar® aramid fibers. The ARACON fibers are a superior lightweight alternative to traditional nickel-plated copper wire for EMI shielding. Replacing standard wire with ARACON offers significant weight savings without sacrificing EMI performance, as well as other benefits that copper and alloy wires cannot match.

The advantageous physical properties and manufacturing characteristics of Osprey Controlled Expansion (CE) alloys are currently being exploited in a variety of electronic applications. The ability to tailor the coefficient of thermal expansion (CTE) values of these alloys to ceramic circuit boards and components operating at high frequencies, combined with...

Ideal for Devices Used in WiMAX, Military and Space Applications; Hermetic Surface Mount Package Allows Products to Operate at Higher Frequencies

The setups presented are essentially of two types - thin dielectric sheet testers and z-axis testers. These are the tools that are employed to independently measure the components of the substrate dielectric constant. It is supposed that suitable propagation models may use this information to better predict propagation mode...

Improving VSWR is typically an iterative trial-and-error exercise when utilizing either frequency or time domain information. For example, while circuit modifications which decrease time domain reflectometry (TDR) "bumps" (discontinuities) are generally a good thing, decreasing a specific TDR bump does not necessarily improve VSWR within a frequency band of...

X2Y® technology is a new balanced component capable of high frequency performance across a broad frequency range. The component uses a standard ceramic capacitor with subtle, but important modifications to its structure. These structural changes create a circuit inside the capacitor that is capable of broadband electromagnetic interference (EMI)...

In the telecoms and other RF component markets, today's climate means that there can no longer be a trade-off between cost and performance - the designer needs to achieve both. Temex has recognized this fact and addressed it through the evolution of two new generations of materials on which...

A number of factors are driving the design of high speed digital packaging. At the assembly level, metal boxes are the dominant configuration due to mounting and interconnect constraints. The next assembly connectivity is accomplished through cables, requiring coaxial connectors. Since a variety of companies manufacture many of the...

The CMC-SOIC8 ceramic SOIC8 surface-mount package is ideal for packaging RF/microwave MMIC and discrete devices for applications from DC to 18 GHz. This new addition to CMC's standard product line is fabricated using aluminum nitride (AlN), a ceramic material with thermal conductivity of 180 W/m-K, about 10 times higher...
