An RF printed circuit board is a circuit board designed specifically for radio frequency (RF) applications. These boards use special materials and designs to reduce signal loss, interference, and to increase signal transmission and reception. They may also have additional features such as shielding, grounding, and impedance matching to enhance the performance of the RF circuit.
Material selection is an important consideration for RF PCBs. RF PCBs typically use specialised materials such as Rogers which have low dielectric constants and loss tangents, as well as good thermal stability and durability.
