Little knowledge - High frequency PCB
The increasing complexity and rapid change of electronic components require faster signal flow rates, and thus higher transmission frequencies.
A high-frequency PCB can meet your needs when incorporating a special signal requirement into your multilayer PCBs.
It offers a frequency range of 500MHz - 2GHz, making it ideally suited for high-speed designs, as well as radio frequency (RF), microwave and mobile applications.
High frequency PCB can also provide faster signal flow rates which is of great necessity in increasingly complex electronics.
