The design of high-frequency RF cables is more compact in order to allow for use at high frequencies. Features that lead to high levels of signal attenuation, impedance mismatch, and distortion are also minimized. In addition, specialized materials like Teflon for insulation and silver plating for the conductors are used to increase the performance of the cable. These types of cables are important for use in microwave communication, satellite systems, and during high speed data transfer
