Resistance integrated coupler between databus and terminal device having databus windings with high resistance wire with resistance being 1.5 times databus cable nominal characteristic impedance

摘要

A system and method for constructing a resistance integrated coupler adapted to be coupled between a data bus and a terminal device. The system and method includes the steps of calculating a desired resistance of a set of data-bus windings, wherein the desired resistance is substantially (1.5xZo), wherein Zo is a selected data bus cable nominal characteristic impedance; winding the set of data-bus windings to form a first part of the resistance integrated coupler using a specified amount of high resistance wire, the specified amount of high resistance wire having a total resistance substantially equal to the calculated desired resistance; and winding a set of terminal device windings to form a second part of the resistance integrated coupler. The resistance integrated coupler is constructed substantially in accordance with the guidelines of MIL-STD-1553B.
