Abstract
A transformer bus coupler, which connects a transceiver to a data bus without impedance discontinuities. The transformer bus coupler maintains the voltage-to-current ratio of signals as they enter and leave the coupler by providing a shunt circuit that attenuates the current of these signals by the same ratio that the series elements of the coupler attenuate the voltage. The result is an avoidance of impedance discontinuities, which would otherwise result in the signal reflections and the loss of signal fidelity experienced by prior art data bus couplers.
