Arlon 25N and 25FR are woven fiberglass reinforced, ceramic-filled composite materials engineered for use in microwave and RF multilayer printed circuit boards. Combining a non-polar thermoset resin system with a controlled-expansion ceramic filler, 25N and 25FR offer low dielectric constant and loss combined with a low Thermal Coefficient of Dielectric Constant (TCEr) for signal stability over a wide ambient temperature range. Designed for use in multilayer packages, 25N and 25FR offer prepregs that are identical in chemical composition and physical properties with their copper clad laminates for a completely homogeneous finished package for optimal signal integrity.The low dielectric constant (Er) and loss properties, low thermal coefficient of dielectric constant (TCEr), and excellent physical stability characteristics offered by 25N and 25FR materials make them ideal for wireless and digital applications, such as cellular telephones, down converters, low noise amplifiers, antennas and other advanced des ign circuits.Processing for 25N and 25FR materials is consistent with processing for standard high temperature thermoset based printed circuit board substrates.

AD1000 is a high dielectric constant substrate that permits circuit miniaturization, compared to traditional low loss materials. It is especially beneficial for power amplifiers, filters, couplers and other components using low impedance lines.AD1000 is a woven glass reinforced laminate. This allows for Greater Dimensional Stability and Mechanical Robustness than other 10 Dk Products. Its large panel size is also advantageous for “multi-circuits per panel” processing.

CuClad 250(Er=2.40–2.60) uses a hi gher fiberglass/PTFE ratio to prov ide mechanical properties approac hing those of conventional subs trates. Better di mensional stabi lity and lower thermal expansi on in all di rections are other si gnificant benefi ts. The el ectrical properti es of CuCl ad 250GT and CuClad 250GXare tested at 1MHz and 10GHz respectively. For cri tical perform ance appli cations, CuCl ad products may be specified with an “LX” testing grade; this designates that each sheet will be tested individually, and a te st report will be issued with the order.

The AD Series™ antenna materials from Rogers Co rporation are high performance, specialty materials that are specifically engineered and manufactured to meet the demands of today’s wireless antenna markets. Increased antenna performance requirements are a constant trend in the market today. Rogers has the materials needed to meet the design needs of this market both today and into the future.

Rogers RO3000® series bondply is an undensifi ed version of RO3000 laminates that can be used to process highly reliable, homogeneous RO3000 multi-layer boards (MLB’s). The bondply is used in a manner analogous to prepreg in FR-4 constructions and, once bonded, becomes the equivalent of a normal RO3000 core layer.

CuClad 217(Er=2.17, 2.20) uses a low fiberglass/PTFE ratio to provide the lo west di electric constant and di ssipation factor available in fiberglass reinforced PTFE based laminates. Together, these prop erties offer fas ter signal propagati on and higher signal/noise ratios.

TMM® thermoset microwave materials are ceramic, hydrocarbon, thermoset polymer composites designed for high plated-thru-hole reliability stripline and microstrip applications. TMM laminates are available in a wide range of dielectric constants and claddings. The electrical and mechanical properties of TMM laminates combine many of the benefits of both ceramic and traditional PTFE microwave circuit laminates, without requiring the specialized production techniques common to these materials. TMM laminates do not require a sodium napthanate treatment prior to electroless plating.

RT/duroid® 5870 and 5880 glass microfi ber reinforced PTFE composites are designed for exacting stripline and mi crostrip circuit applications.

RT/duroid® 6002 microwave material was the first low loss and low dielectric constant laminate to offer superior electrical and mechanical properties essential in designing complex microwave structures which are mechanically reliable and electrically stable.
