Radio Frequency PCB 8 Layers Mixed Pressure PCB

 What is RF PCB?

RF is Radio Frequency, which refers to radio frequency, a signal with a very high frequency. Depending on the requirements for PCB performance indicators, it can be ordinary FR4 epoxy glass fiber, or special microwave substrate such as Teflon.
　　RF circuit board standard:
　　 1. In the PCB design of low-power RF, standard FR4 materials are mainly used (good insulation properties, uniform material, dielectric constant ε=4, 10%).
　　2. In the RF PCB, each Electronic Components should be arranged closely. Surface-Mount (SMT) & BGA Assembly ensure the shortest connection between each component.
　　3. For a mixed signal high frequency mixing pressure plate PCB, the RF part and the analog part should be far away from the digital part (this distance is usually more than 2cm, at least 1cm), and the ground of the digital part should be separated from the RF part.
　　4. When selecting components to work in a high frequency environment, use high frequency mixing pressure plate as much as possible. This is because surface mount components are generally small in size and the component leads are very short.
