PTFE High Frequency Basic Panel

High frequency is an inevitable trend in the development of the communication industry. Materials traditionally used in low-frequency communication circuits have been unable to meet the electrical performance requirements required for high-frequency communication. Accurate and stable dielectric constant (DK) and smaller dielectric loss (DF) are important foundations for the development of high-frequency communications. PTFE is a resin material with the lowest dielectric constant and dielectric loss coefficient. It has incomparable advantages in dielectric properties and is the best choice for high-frequency communication circuit materials.
