RF – Radio frequency PCBs
Radio frequency (RF) and microwave (MW) circuits can be found in wireless products from handheld devices for medical and industrial applications to advanced communications systems for base stations, radar and global positioning.
When producing radio frequency PCBs, it is important to think about how to control the signals using (i) materials types and material characteristics (loss tangent / Df and dielectric constant / Dk) (ii) low profile copper foils (iii) weave styles and (iv) how we layout the copper circuitry.

"I am extremely satisfied with the quality of the PCBs you manufacture. The solder pads on each board are very smooth and the connections are very strong. I have worked with other manufacturers before, but the quality was always subpar. Since switching to SprintPCB, the quality of my projects has significantly improved. Thank you for your outstanding manufacturing process!"

FAQ about Radio frequency PCBs
A Radio Frequency (RF) PCB is a type of printed circuit board designed specifically for high-frequency applications in the RF and microwave frequency range, typically ranging from 3 MHz to 100 GHz.
RF PCBs have specific design requirements and construction techniques that differ from regular PCBs. They are designed to handle high-frequency signals with minimal signal loss and interference, and are manufactured with materials that are specially chosen for their electrical and thermal properties.
The materials used in the manufacturing of RF PCBs include specialized high-frequency laminates, copper cladding, and substrate materials. The selection of materials is based on their dielectric constant, loss tangent, and thermal conductivity.
RF PCBs are tested using specialized equipment such as network analyzers, spectrum analyzers, and time-domain reflectometers to ensure their electrical performance meets the specifications required for their intended use.
RF PCBs are commonly used in wireless communication devices such as cell phones, Wi-Fi routers, and satellite communication systems, as well as in medical and military equipment, navigation systems, and scientific instruments.
