Knitted Wire Gaskets For Electronic EnclosuresTechMESH Knitted Wire gaskets from Leader Tech make reliable electrical contact between parallel metallic surfaces in broad ranging commercial and military-grade electronic enclosures. When installed between gaps, seams and openings the gaskets create a high attenuation EMI shield, thereby preventing unwanted interference from leaking into the environment. TechMESH gaskets provide a shielding effectiveness up to 130dB in the E-Field and up to 80dB in the H-Field and are available in four standard profiles and 48 different sizes. Each profile can be ordered in either an all mesh or an elastomer core enclosed by a mesh. This configuration insures preasure on the gasket without crushing the mesh. The gaskets are available in a choice of three materials: tin-plated copper-clad steel, Monel and aluminum. Additionally, gaskets can be supplied on spools of 25 feet or cut to exact application specifications.

For more information, visit New Ni/al-Filled Elastomer Gaskets New EMI shielding materials that use low transfer impedance nickel/aluminium (Ni/Al) particle filled elastomers have been developed by Chomerics Europe, offering industry-leading levels of shielding effectiveness. Available as moulded, extruded and form-in-place (FIP) gaskets, the new materials also offer high stability and excellent galvanic compatibility with aluminum. This means that pitting due to galvanic erosion is significantly reduced compared to applications that use silver/aluminum (Ag/Al) filled elastomers. The high reliability levels of the new gaskets help to reduce field service and warranty needs, giving total cost of ownership savings in the region of 30% to 40%. The materials can also overcome the requirement to apply Ni or Tin (Sn) plating to aluminum flanges and housings, and may alleviate the need to incorporate secondary outboard non-conductive gaskets, and complicated partial flange painting operations. For more information, visit Diode Connectors Offer EMI/RFI, EMP Protection Sabritec now offers a complete line of transient volatage suppression protection solutions embedded within the connector shell utilizing surface mount technology diodes. EMI/RFI and EMP protection can both be integrated into a connector with only a small increase in length over the non-filtered version. The incorporation of SMT components can offer space and weight savings based on connector application requirements. Sabritec's design approach for diode connectors is unique, mounting diodes around the outside of the contact arrangement on a multi-layer circuit board within the connector. Sabritec uses standard military or commercial grade diodes, located outside the contact arrangement to allow for size and shape options so the power/pulse width capability is preserved. The circuit traces from the contact to the diode are kept as wide as possible and are sandwiched between ground planes, providing a very low characteristic impedance strip line configuration thus eliminating any ringing of pulse response.

For more information, visit Agilent's New PNA-X Network Analyzer OptionAgilent Technologies Inc. is offering Option 028 to its PNA-X series of microwave network analyzers. The new option allows highly accurate, source-corrected noise figure measurements of amplifiers, frequency converters and mixers up to 50GHz. The PNA-X, configured with Option 028, is the only network analyzer in the industry to correct for the effects of imperfect system source match. This is accomplished by using vector error correction to remove mismatch errors, and an ECal module as an impedance tuner to remove noise-parameter-induced errors Agilent's Option 028 uses the PNA-X's standard S-parameter receivers and Agilent's unique source-correction technique to make noise figure measurements up to 50GHz. For devices with less than 30dB of excess noise, an external preamplifier and filter are required. For noise figure measurements up to 26.5GHz, an additional option (Option H29) is available that offers an internal low-noise receiver for 50GHz PNA-X instruments. Option H29 eliminates the need for an external preamplifier and filters, while making the setup as easy as that required for measuring S-parameters.
