Title:
通信装置及び通信装置のためのカプラー
Document Type and Number:
Japanese Patent JP5383749
Kind Code:
B2
Abstract:
An apparatus for high frequency electrical line communication includes a transmitter, a receiver, a modem, and a coupler at each of two or more locations along an electrical line. The couplers have capacitive circuits serially connected with an air-core or dielectric-core transformer. The capacitive circuits resonate with the transformer at a preselected frequency. The coupler eliminates noise and is matched to the characteristic impedance of the line at the preselected frequency, which linearizes communication on the line and allows high speed data and voice communication over long distances.
