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.

High Speed Design Frequency PCB Board Special high electromagnetic frequency circuit boards, in general, can be defined as the frequency of the high frequency of 1GHz. Its physical properties, precision, technical parameters required is very high, commonly used in automotive anti-collision systems, satellite systems, radio systems, etc.
The basic characteristics of a high frequency board material requirements are the following:
(1) dielectric constant (Dk) must be small and very stable, usually the smaller the better signal transfer rate and the dielectric constant of the material
Inversely proportional to the square root of high dielectric constant is likely to cause the signal propagation delay.
(2) the dielectric loss (Df) must be small, mainly affect the quality, the smaller the dielectric loss signal transmission of the signal loss is smaller.
(3) as far as possible consistent with the coefficient of thermal expansion of the copper foil, copper foil separated because of inconsistency will cause changes in the hot and cold.
(4) to low water absorption, high water absorption will affect the dielectric constant and dielectric loss when damp.
(5) Other heat resistance, chemical resistance, impact strength, peel strength, etc. must also be good.
