Air is a near perfect dielectric medium allowing a signal to propagate through it at approximately the speed of light. However, an air dielectric is impractical for use as a cable insulation as it provides no structural integrity. Thus, manufacturers have to resort to using materials with higher dielectric constants (lower propagation velocity) to meet physical requirements.

NEWcel® is the perfect solution. Typical coaxial, triaxial, and twinaxial cables are manufactured using low dielectric constant (2.0 – 2.6) materials that possess inherently better electrical properties than standard insulation material such as PVC. Using highly controlled extrusion processes, these materials are foamed yielding a dielectric medium with a high air concentration. The result of this process is a significantly reduced dielectric constant (1.45 – 1.8) that approaches the nearly ideal properties of air without sacrificing structural integrity. This results in a significant capacitance reduction while providing the customer with the choice of reduced diameter/same attenuation or same diameter/reduced attenuation.

Product Advantages

• Reduces Attenuation
• Reduces Cable Size
• Reduces Capacitance
• Wide Temperature Range

SuperFlex Wire & Cable is a "high tech" product pioneered and developed by Calmont for the exacting commercial and military markets. Specially compounded and plasticized polyvinyl chloride insulations applied over ultra fine stranded wire yields a finished wire with a longer flex life and a higher flexure index level than that attainable with ordinary PVC insulated wire.

SuperFlex construction is available with Nylon as a jacket or insulation replacement for the standard PVC. This provides increased impact and tensile strength which only can be realized through the use of Nylon.

SuperFlex wire and cable insulated with polyethylene is also available. Polyethylene offers good electricals at a low cost insulation. The dielectric constant of 2.3 and dissipation factor of 0.0002 are stable from 60 Hz to 10⁶ MHz

Calmont is your first source for Litz Wire, with or without EMI shielding. For applications requiring high current, high frequency propagation with a minimum of power loss, Litz Wire is likely the ideal choice. Made from a high number of fine, separately insulated strands specially braided or woven together for reduced skin effect and hence lower resistance to high frequency currents for lower RF losses, Calmont can offer your custom design with a variety of insulating and jacketing materials.

Applications:

• One of the best products for high flex life and high strength applications, including: critical life support monitoring, sensor leads, and the continuous flexing in computer peripheral equipment
• Telecommunications, dental technology, biological research, test leads and vital ground support systems

Rotman Lens Designer™ (RLD^™) software package is a tool for the design, synthesis, and analysis of Rotman Lenses and their variants. It is based on Geometrical Optics combined with the classical Rotman Lens design equations. It is intended for rapid development and analysis of Rotman Lenses given several physical and electrical input parameters. RLD generates the proper lens contours, transmission line geometry, absorptive port (dummy port) geometry, provides an approximate analysis of performance, and generates geometry files for import into Remcom's XFdtd^® for further analysis and fabrication.

RLD System Requirements

• Windows 2000 or XP
• Red Hat Enterprise Linux 4 or higher
• 1024x768 minimum resolution
• 64MB or higher OpenGL compliant video card.

RLD Features

RLD^™ creates lens designs based on typical input parameters. An extensive range of output values may be displayed for a given design. Some of the main input and output parameters are listed below.

Inputs:

• Type of Lens - microstrip or stripline
