High Frequence PCB
The High Frequence PCB can meets your demands when the electronic devices need special signal. It offers a frequency range of 500mhZ-2ghz, which is well suited for high-speed design and higher transmission frequencies such as radio frequency (RF), microwave and mobile applications, as well as faster signal flow rates, in line with the current development trend of high-frequency electronic equipment. Communication products such as satellite systems and mobile phone receiving base stations have great demand for high-frequency circuit boards.
 

Features Of High Frequency PCB Boards


(1)They have a low dielectric constant ( DK) relatively stable,  and have a tight tolerances. Generally speaking, the smaller the DK value, the better. The signal transmission rate is inversely proportional to the square root of the material's dielectric constant, and high dielectric constant is likely to cause signal transmission delay.
(2)The dielectric loss (DF) is very small. As the smaller the dielectric loss, the smaller the signal loss.
(3)Not easy to absorb water, having strong  moisture resistivity.
(4)Excellent heat resistance, chemical resistance and peel strength.
