HighSpeed and HighFrequency

Due to the steadily increasing transmission frequencies of electronic components, the need for low-loss in the frequency range of several GHz, high-frequency signal transmission between the components has become extremely important. Inadequate transmission lines lead to reflections and thus to undesirable effects at the end of the line. Signal source + transmission line + receiver must have the same resistance (impedance).

PCBs with defined impedance and transmission characteristics usually based on special materials:

• PTFE containing and PTFE free materials with extreme low loss factors
• Low dielectric loss
• High or even low dielectric constant
• Mixture buildups with different performances (e.g. conventional FR4 in combination with special RF / HF materials)
• Special base copper and plating, as well as special surface finishing best suitable for high-performance RF and Highspeed applications
