Quick-Mount, Low Force Metal Gasket
Omega Shielding Products’ high-endurance 99-940-WT gasket is engineered for heavy-use EMI shielding and grounding applications. The symmetrical design of the gasket offers low compression resistance and reliable electrical contact between mating surfaces with gaps ranging from 0.1 inch (2.5mm) to .06 inch (1.5mm).
Installation is fast and easy by way of a peel-and-stick instant tac adhesive strip on the underside of the gasket. Additionally, the free end of each gasket finger features a fold-under lip that greatly reduces surface friction as the gasket is compressed. Omega’s 99-940-WT is in stock with a bright finish and can also be ordered with one of 10 surface finish and plating options.

Tekmark Real-time Spectrum Analyzers
Tektronix, Inc. has released the RSA6100A series of real-time spectrum analyzers that provides a combination of real-time performance, capture bandwidth, and dynamic range to meet the needs of a broad range of cutting-edge digital RF applications.
DPX waveform image processor technology transforms volumes of real-time data to produce a live RF spectrum presentation that reveals previously unseen RF signals and signal anomalies. Live RF is achieved by improving the spectrum measurement rate nearly 1000 times compared to the fastest swept spectrum and vector signal analysers (VSA).
The first offerings in the new RSA6100A series of real-time spectrum analyzers – the 6.2GHz RSA6106A and 14GHz RSA6114A – provide industry-leading 110MHz real-time bandwidth simultaneous with 73dB spurious-free dynamic range. The RSA6100A series provides world-class capabilities ideally suited to the needs of a broad range of digital RF applications, from power amplifiers for advanced cellular radios to the latest pulsed radar signal.

Beryllium-Free EMI Shielding Material
Laird Technology’s Recyclable Clean Copper™ products meld strong stability and tensile strength with high levels of thermal and electrical conductivity, making it suitable for utilization in both grounding and shielding applications at a cost that is comparable with traditional metal EMI shields.
Shielding effectiveness is similar to other copper alloys with values over 100dB shielding effectiveness readily achieved. Recyclable Clean Copper is fully compliant to EU Directive 2002/95/EC and alleviates the environmental, safety and segregation concerns associated with the traditional use and recycling of beryllium-based copper alloys.
This alternative material exhibits better stress relaxation properties than many other solutions, allowing it to maintain pressure longer at contact points resulting in higher end product quality and longer system life spans. Stress relaxation is measured in percentage of stress remaining after 1000 hours at 150C. This gasket material is characterized by superior yield strength (over 1000MPa) compared to other common copper alloys.
