Generally speaking, high frequency can be defined as the pre-rate above 1GHz. The most commonly used high-frequency circuit board substrates are fluorine-based dielectric substrates. For example, polytetrafluoroethylene (PTFE) is usually called Teflon, which is usually used above 5GHz. , In addition, FR-4 or PPO substrate is also used, which can be used for products between 1GHz-10GHz. The physica...
