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 to 81 GHz where excellent electrical performance and cost efficiency is 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 fibre 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.
The laminates also have a UL-V0 flame-retardant rating with a low water absorption that results in little variation in RF performance through environmental exposure. They are available in three panel sizes: 610 x 457 mm, 610 x 533 mm, and 1219 x 914 mm.
