Hello everyone,
Good day!
Today, we’re highlighting a 4-layer high-frequency PCB designed for ultrahigh-frequency coupler applications. This PCB is constructed using 2 cores of 0.813mm (32mil) RO4003C and 1 sheet of RO4450F prepreg, ensuring exceptional performance for high-frequency needs. Below, you’ll find the detailed stack-up for reference. |

Multilayer Rogers high-frequency PCBs are typically constructed entirely from high-frequency materials, including specialized prepreg adhesives. As widely recognized, the RO4003C family offers six core thickness options, ranging from 8mil (0.203mm) to 60mil (1.524mm), providing flexibility for various design requirements. |
