  • Cutover apparatus and methods for switching a signal between two transmission media
    Patent number: 5544197
    Abstract: A system and methods are provided for switching a signal from a first transmission media having a characteristic impedance to a second transmission media. The system includes a driver for driving a signal, the driver having a driver input having a high impedance relative to a characteristic impedance of the first transmission media and the driver having a driver output having an impedance equal to the characteristic impedance of the first transmission media. A first switch couples the driver output either to the first transmission media or to the second transmission media and couples a signal from the first transmission media, which is coupled to the driver input, either to the first transmission media or to the second transmission media.
