Combined Laminates Provide Matched 6.15-Dk Multilayer System Solution

Rogers Corporation has developed the perfect prepreg match to its popular RO4360™ laminates: RO4460™ prepregs. Both materials feature consistent dielectric constant (Dk) of 6.15 ± 0.15 and low dielectric loss of 0.003 at 2.5 GHz. Together, they form an ideal system for fabricating compact, cost-sensitive multilayer amplifiers, antennas, and other high-frequency circuits where space is at a premium. As with RO4360 laminates, RO4460 prepregs are ceramic-filled, thermoset materials reinforced by glass fibers for excellent mechanical stability. Compared to PTFE substrates, the high DK of Rogers RO4360 laminates and RO4460 prepregs allows designers to reduce the size of high-frequency circuits by typically 20% to 30%. The laminates and prepregs support smaller size circuits with excellent thermal conductivity of 0.8 W/m-K for effective thermal management.
