Rogers Advanced Circuits Materials Division (ACM) introduces two new laminates to the market at the IEEE Radio & Wireless Week expo at the Renaissance Glendale Hotel & Spa in Glendale, Arizona January 17-18, 2011. Rogers (Booth #2) features its new XT/duroid™ 8000 series high performance thermoplastic laminate materials along with its new RT/duroid® 6035HTC high thermal conductivity laminates. XT/duroid 8000 Series Laminates Rogers XT/duroid 8000 Series includes XT/duroid 8000 laminates for simpler multilayer designs (less than 6 layers) and XT/duroid 8100 laminates for constructions consisting of six or more layers. Highly reliable and halogen-free flame retardant, XT/duroid laminates are thermally and chemically robust with melting points higher than PTFE materials and an estimated maximum Relative Thermal Index (RTI) greater than 210°C (410°F), making them well suited for rugged military and aerospace applications, including airborne lightning strike protection circuits, phased-array antennas and unmanned aerial vehicles (UAVs). Rogers' new XT/duroid 8000 laminates feature a z-axis dielectric constant of 3.23 ±0.05 at 10 GHz and a dissipation factor of 0.0035 or less at 10GHz. They deliver stable electrical performance over wide frequency ranges, with a low thermal coefficient of dielectric constant of +7ppm/°C from -50 to +150°C. For complex multilayer circuit constructions requiring excellent stability, XT/duroid 8100 laminates have a reinforced woven-glass resin system for added dimensional stability. That makes them capable of supporting multilayer circuits while providing the thermal and chemical ruggedness, as well as outstanding electrical performance, of XT/duroid 8000 laminates. Rogers' new XT/duroid 8100 laminates feature z-axis dielectric constants of 3.54±0.05 (.002") & 3.32±0.05 (.004") at 10GHz and dissipation factors of 0.0049 (.002") & .0038" (.004") at 10GHz. They deliver stable electrical performance over wide frequency ranges, with a low thermal coefficient of dielectric constant of +9ppm/°C from -50 to +150°C. Both XT/duroid 8000 and 8100 laminates are available with a dielectric thickness of 0.002 in. (0.0508 mm) with 0.5-oz. low profile reverse treated electrodeposited copper foil cladding. XT/duroid 8100 is also available with dielectric thickness of 0.004 in. (0.1016 mm). RT/duroid 6035HTC Laminates Rogers new RT/duroid® 6035HTC is a high-thermal-conductivity (HTC) laminate material engineered for low loss in high-power circuits. With a thermal conductivity of 1.44W/m-K and a loss tangent of 0.0013 @ 10GHz, this combination of high thermal conductivity and low dielectric loss translates into improved amplifier performance. Rogers RT/duroid 6035HTC laminates feature a relative dielectric constant of 3.5 at 10 GHz, making them suitable for a wide range of circuits, including amplifiers, couplers, filters, and power combiners/dividers employed in avionic and other military and high reliability systems. Improved drillability and extended tool life is an advantage of the advanced filler system in comparison to alumina-containing circuit materials. RT/duroid 6035HTC laminates are available in a variety of dielectric thicknesses and cladding options to support a wide range of high frequency circuit applications. www.rogerscorp.com
