Radio Frequency and Microwave PCBs are a special and innovative type of PCB, designed to operate on signals in the Megahertz to Gigahertz frequency ranges for communication signals in everything from smartphones to military radars. Very specific materials and technology that are not available in many factories are required to build the PCB equipment.
The right material, stack-up and via structure in combination with controlled impedance enable RF and MV designs to minimize signal return loss, noise and crosstalk.
The low-loss tangent allows high-frequency signals to travel fast through the PCB with controlled impedance. RF and MV designs must avoid return signal seeking the route with the least inductance.
Hybrid or Mixed dielectric stack-ups combining FR4 with Low loss & Low dielectric constant materials are often used for RF and MV boards to lower the cost.
PCB structure is extremely stable in high-temperature environments. If used in analog applications, these PCBs can operate at 40 GHz.
With mixed dielectric stack-ups and with the use of Blind and Buried via structures it is possible to integrate RF/MV with analog and digital signals and components.
RF microwave PCBs are a specialized type of PCBs designed to handle high-frequency signals in the RF and microwave frequency range with minimal signal loss and maximum signal integrity. They are used in a wide range of electronic applications such as wireless communication systems, satellite communication systems, radar systems, and other high-frequency electronic systems. Their design and production require specialized knowledge and experience to ensure the expected performance.

With the advancement of electronic technology, the requirement of consumers and factories are more demanding every day. The PCB manufacturers must significantly increase the capacities of their products to accommodate this progress and always provide more potential to the R&D departments. Modern Radiofrequency/Microwave boards are pushing the limits of contemporary electronics
An RF (Radio Frequency) Microwave PCB (Printed Circuit Board) is a type of PCB designed to handle high-frequency signals in the RF and microwave frequency range, typically between 1 MHz and 100 GHz. These PCBs are used in a wide range of electronic applications such as wireless communication systems, satellite communication systems, radar systems, and other high-frequency electronic systems.
