RF PCB introduction:
RF is Radio Frequency, referring to the radio, a high-frequency signal.
For performance index of PCB, it can be an ordinary FR4 epoxy glass fiber and also Teflon
and other dedicated microwave substrates.
RF board standards:
1, In the design of miniwatt RF PCB, main material is standard FR4 (Good insulation characteristics
uniform material, dielectric constant ε = 4,10%).
2, In the RF PCB, every component should compact configuration to ensure that the shortest connection
between the every component.
3, For a mixed-signal PCB, RF and analog section should stay away from digital part
(This distance is usually more than 2cm, at least 1cm), the digital part of the ground should be
separated from the RF part.
4, To choose the components working in high frequency environment should use of surface-mount component as far as possible. Because the surface-mount component is small volume generally and the pin of component is very short.
