An isolating transmission line transformer having a core 71, two ports (1 and 2) and a transmission line, the transmission line having two conductors 73 and 76 connected in series to the respective ports on opposite sides of the core. This arrangement provides d.c. isolation between the ports. The conductors are arranged side by-side though or around the core, and each executes a single turn or winding through or around the core. The conductors may be twisted about each other as they pass through or around the core. The core can typically be binocular having two bores 74 and 75 but can also be toroidal, or a pot core. The first port is for connection to a data source, and a second port for connection to a transmission or data receiver line. It is important that the port characteristic impedances substantially match the respective impedances of the data source or receiver and the transmission line. |
