RF Design
With the introduction of ULTRALAM 1000 series woven glass reinforced PTFE laminates, Rogers Corporation extends its ability to offer 'one-stop shopping' for designers who need all types of high frequency printed circuit board laminates. ULTRALAM 1000 series materials match the dielectric constant and loss tangent characteristics of other woven glass PTFE laminates, allowing customers to secure an additional materials source for ongoing programs without revising board designs.
The laminates are available in sheets up to 1,22 x 3,05 m in size, suitable for making large panel antennas, as well as in sizes of 30,5 x 46 cm, 61 x 46 cm and 61 x 91,5 cm. Standard thicknesses include 0,51 mm, 0,79 mm, and 1,58 mm for dielectric constants of 2,171, 2,50 and 3,0. Standard electrodeposited copper foil claddings are 14 g (17 µm) and 28 g (35 µm). These configurations are targeted to common antenna and amplifier applications.
Glass fibres are oriented in the X/Y plane for dimensional stability and lowered thermal expansion. Stable electrical properties versus frequency offer repeatable design performance and the materials' chemical and mechanical properties allow normal handling and processing.
These laminates are intended for typical applications in wireless antennas, cellular base stations, LAN systems, automotive electronics, satellite TV receivers, RF and microwave components, radar systems, mobile communications systems and microwave test equipment. Fabrication uses standard PTFE processing techniques.

A cordless ESD (Electrostatic Discharge) wrist strap does not work by grounding the person in the same way as a traditional wired wrist strap. Instead, it works by reducing or balancing the static charge on your body so that you are less likely to discharge electricity into sensitive electronic components.
