The RO4835IND Lo Pro from Rogers Corporation are Thermoset RF Laminates that are specifically designed to operate for short-range (<30 m) industrial radar applications from 60-81 GHz where excellent electrical performance and cost-efficiency are equally important. The Lo Pro Laminates offer a typical dielectric constant of 3.48 and a dissipation factor of 0.0037 with stable performance over a wide frequency range. They have a transition temperature of over 280°C. These laminates integrate an expanded weave fiber that provides an excellent Dk uniformity with tight quality control that offers a low Dk variation from lot to lot.
The RO4835IND Lo Pro laminates are compatible with standard epoxy/glass (FR-4) processes and have a higher fabrication yield rate compared to conventional PTFE-based laminates. They ensure suitability for both cap layer on multilayer FR-4 board design and inner layers for a multi-layer design. They also have a UL-V0 flame retardant rating with a low water absorption that results in a little variation in RF performance through environmental exposure. These laminates are available in three-panel sizes: 24 x 18 inches, 24 x 21 inches, and 48 x 36 inches and are ideal for 60-81 GHz industrial radar applications.
