Transmission line form in high frequency PCB design

Both transmission lines and waveguides can be used as carriers for high frequency signal transmission, while microstrip lines and strip lines in TEM transmission lines and Substrate Integrated Waveguide in Waveguide structures are applied in the design of high frequency PCBs.

High frequency PCB wiring skills

The radiation intensity of the signal is proportional to the wiring length of the signal line. The longer the high-frequency signal lead is, the easier it is to be coupled to the components close to it. Therefore, the high-frequency signal lines such as the signal clock, crystal oscillator, DDR data, LVDS line, USB line, HDMI cable and so on are required to be as short as possible.

Blind Vias

Blind Vias is to connect an outer layer to at least one inner layer

Advantages of Rogers PCB

Good impedance control

With low dielectric loss, low signal loss

Suitable for harsh environmental conditions.

It is very cost effective in circuit manufacturin

Rogers PCB showed significantly less water absorption and improved thermal management.

The coefficient of thermal expansion of the RO4000 material is similar to that of copper, which provides dimensional stability
