RF PCB – Radio Frequency Printed Circuit Boards. In general terms, the PCB industry considers an RF circuit board to be any high frequency PCB that operates above 100MHz.
Within the radio frequency class, anything above 2GHz is a Microwave PCB.which they operate. Microwave PCBs are classified as any RF circuit board operating above 2GHz.
RF circuit boards and Microwave PCBs are used for communication signals in any application that requires receiving and transmitting radio signals. For example, some common applications are cell phones and radar installations.Some of the suppliers of laminate / dielectric materials we utilize are: Isola, Nelco, Rogers & Taconic.
A hybrid printed circuit board (PCB) multilayer is a PCB that uses dissimilar materials with the intent of optimizing electrical performance and improving system reliability focused towards high-frequency RF applications. The biggest challenge when manufacturing this type of PCB is managing the different coefficient of thermal expansion (CTE) properties of the dissimilar circuit materials both during PCB fabrication and component assembly.
Typically these designs include a combination of FR-4 material and PTFE laminates which allows a designer to condense both RF functionality and RF functionality on the same PCB which can reduce both the footprint of the device and the costs.
