A Discussion of Passive Components for Broadband Power Line Communication Coupling Circuits

This paper aims to analyze how the characteristics of passive components impact the design of power line communication (PLC) coupling circuit for broadband applications. Based on a measurement results, we show that plated through-hole and surface mount device components present distinct behaviors in the higher frequencies. Consequently, we point out that the implementation type of passive components is particularly important when the design have to result in impedance matching and flat frequency response for minimizing distortions in the coupling process in high frequencies.
