RF PCB Layout: Interconnect Losses

Your trace geometry and layer stack will have a major effect on signal integrity as you route high frequency analog signals throughout your board. Newer designers will likely default to a microstrip geometry, possibly with guard vias to provide isolation between different circuit blocks and to suppress radiated emissions. The question of which trace geometry to use is about more than isolation; it is also about avoiding losses due to dielectric absorption, roughness losses, and scattering from your PCB substrate. The alternative to using microstrip transmission lines is to use stripline transmission lines. Routing striplines on a dedicated interior layer [...]

Why Hitechpcb?

There are thousands of PCB manufacturers  and PCB assembly factories in China, why should I choose Hitech? Good Pricing We have 2 factories by far, and each one is dedicated in one aspect of PCB production, the workers are more professional and skillful in specified area, then the efficiency is higher and the cost is lower; also, our inland factory employs cheaper labor forces and housing than Shenzhen area, so the cost is cheaper obviously. Quick Delivery Devilry is quick–5-8 working days normally, 2 working days with a premium. High quality We fully understand quality comes first. All our factories [...]

Material Selection for High frequency PCB Fabrication

We mostly use high frequency laminates in high frequency PCB. However, these are often difficult to fabricate. Because they must maintain the thermal heat transfer of the application due to the sensitivity of the transmitted signal. So, we need special materials for high frequency PCB manufacturing. When you are selecting a material for High frequency PCB, you must keep the following in mind. Dielectric constant It is the ability of a material to store energy when we apply an electric field. However, it is a directional property which means that it will change with the axis of the material. So, [...]
