FR is Radio Frequency, which refers to radio frequency and high frequency signals. Look at the performance requirements of the circuit board, can be ordinary FR4 epoxy glass fiber, it can also be special microwave materials such as Teflon.
RF board standard:
1. In the PCB design of low-power RF, the standard FR4 material is mainly used (with good insulation properties, uniform material, and dielectric constant ε=4, 10%).
2. In the RF PCB, the various components should be arranged closely to ensure the shortest connection between components.
3. For a mixed-signal PCB, the RF section and the analog section should be located away from the digital-digital section (this distance is usually more than 2cm, at least 1cm), and the ground of the digital section should be separated from the RF section.
4. When selecting a working component in a high-frequency environment, use a surface-mount device as much as possible. This is because surface mount components are generally small and the components have very short leads.
