RO4000® Series High Frequency Circuit Materials (Woven glass reinforced, ceramic filled thermoset)
Rogers RO4000® high frequency circuit materials are glass-reinforced hydrocarbon/ceramic laminates—not PTFE. They combine high frequency performance comparable to woven glass PTFE substrates with the ease—and hence low cost—of fabrication associated with epoxy/glass laminates. The RO4000 advanced circuit material is a woven glass reinforced, ceramic filled thermoset laminate with a very high glass transition temperature (Tg >280°C). Unlike PTFE based microwave materials, no special through-hole treatments or handling procedures are required. RO4003C was designed with a dielectric constant of 3.38. The RO4350B has a dielectric constant of 3.48 and is UL94V-0 rated.
RO4360™ high frequency material offers the same repeatability and reliability as our RO4000 materials with the added benefit of a higher DK of 6.15. This will allow circuit designers to reduce circuit dimensions in applications where size and cost are critical such as power amplifiers, patch antennas, ground-based radar and other general RF applications.
RO4450B™ and RO4450F™ prepregs were developed to enable users to build high frequency multilayers and are based upon the RO4000 series core materials. They are compatible in multilayer constructions with either RO4003C™, or RO4350B™ laminates. RO4400™ prepregs are compatible with the majority of standard FR4 processing practices. Prepreg technical information is provided in the RO4400 data sheet and fabrication guidelines below.
RO4500™and RO4730™ LoPro™ antenna grade laminates extend the RO4000 product series into large volume antenna applications. The ceramic filled, glass reinforced, hydrocarbon based material provides the controlled dielectric constant, low loss performance and excellent passive intermodulation response required for mobile infrastructure microstrip antenna applications.
