  • Multi-layered printed circuit board with transmission line capabilities
    Patent number: 5278524
    Abstract: A multi-layered printed circuit board for mounting and interconnecting the terminals of multi-terminal electronic components. The circuit board mounts the electronic components one side of the circuit board and provides for interconnecting the terminals of the electronic components. A transmission line arrangement is configured from layers of the circuit board for distributing a signal with fast rise and fall times to electronic components mounted on the circuit board. The transmission line arrangement includes a narrow conductive strip surrounded by four constant voltage conductors spaced from the narrow conductive strip by dielectric material.
