RO4350B materials are proprietary woven glass reinforced hydrocarbon/ceramics with electrical performance close to PTFE/woven glass and the manufacturability of epoxy/ glass.
Providing tight control on dielectric constant and low loss while utilizing the same processing method as standard epoxy/glass, RO4350B is available at a fraction of the cost of conventional microwave laminates. No special through-hole treatments or handling procedures are required as with PTFE based microwave materials.
RO4350B materials are UL 94V-0 rated for active devices and high power RF designs.
RO4003 (r = 3.38) and RO4350 (r = 3.48) is the same material for the commercial market development. Woven fiberglass body is immersed in a ceramic plus thermoplastic resin to form a rigid and temperature stable laminate, electrical characteristics suitable for microwave frequencies. Mechanical properties of this material is similar to FR4, can use ordinary FR4 production processing technology, in combination with prepreg RO4403, can make plywood. RO4350 material for the needs UL94V0 grade applications. Compared with the price RO3000 series, RO4000 low-cost microwave circuit applications selective superior.
RT/duroid 5880 high frequency laminates are PTFE composites reinforced with glass microfibers.The randomly oriented microfibers result in exceptional dielectric constant uniformity.
The dielectric constant of these high frequency laminates is the lowest of all products, and low dielectric loss make them well suited for high frequency/ broad band applications where dispersion and losses need to be minimized. Because of its extremely low water absorption characteristics, RT/duroid 5880 laminates are ideal for applications in high moisture environments.
RT/duroid 5880 laminates are easily cut, sheared and machined to shape, and resistant to all solvents and reagents normally used in etching printed circuits or plating edges and holes. RT/duroid 5870 and 5880 laminates have the lowest electrical loss of any reinforced PTFE material, low moisture absorption, are isotropic, and have uniform electrical properties over frequency.
RT/duroid 6002 microwave materials are a low dielectric constant laminate offering electrical and mechanical properties essential in designing complex microwave structures which are mechanically reliable and electrically stable.
The thermal coefficient of dielectric constant is extremely low from -55oC to+150oC (-67°F to 302°F) which provides the designers of filters, oscillators and delay lines the electrical stability needed in demanding applications.
RT/duroid 6006 microwave laminates are ceramic-PTFE composites designed for electronic and microwave circuit applications requiring a high dielectric constant. RT/duroid 6006 laminate is available with a dielectric constant value of 6.15 and RT/duroid 6010LM laminate has a dielectric constant of 10.2.
RT/duroid 6006 microwave laminates feature ease of fabrication and stability in use. They have tight dielectric constant and thickness control, low moisture absorption, and good thermal mechanical stability.
RO3200 series material RO3203 (r = 3.02) and RO3210 (r = 10.2) two composition, suitable for application RO3000 series material but need better mechanical strength of the occasion. RO3200 series material is a combination of PTFE / ceramic with PTFE / woven fiberglass laminated, with good rigidity and RO3000 materials, the material in this series can also be produced with mixed FR4 multilayer MLB
RO3003 high frequency circuit materials are ceramic-filled PTFE composites intended for use in commercial microwave and RF applications. This family of products was designed to offer exceptional electrical and mechanical stability at competitive prices.
RO3003 excellent stability of dielectric constant over temperature including the elimination of the step change in dielectric constant, which occurs near room temperature with PTFE glass materials. Additionally, RO3003 laminates exhibit a low dissipation factor of 0.0013 at 10 GhZ.
