Radio frequency (RF) and microwave PCB’s are a type of PCB designed to operate on signals in the medium frequency to extremely high frequency ranges (megahertz to gigahertz). These ranges are used for communication signals in everything from mobile phones to military radars.
The materials used are advanced composites with very specific characteristics for dielectric constant (Er), loss tangent, and CTE (co-efficient of thermal expansion). These materials can be mixed in the same Stack-Up for optimal performance and economics.
In order to meet increasing demands for Microwave & RF Printed Circuit Boards for our customers all around the world, we have increased our investment over the last few years so that we have become a world class manufacturer of PCBs using high frequency laminates.
