A cable bypass assembly is disclosed for use in providing a high frequency transmission line that connect a chip package on a circuit board to connector spaced apart from the chip package. The bypass cable assembly has a structure that allows for low loss between the chip package and the connector.
A cable bypass assembly is disclosed for use in providing a high frequency transmission line that connect a chip package on a circuit board to connector spaced apart from the chip package. The bypass cable assembly has a structure that allows for low loss between the chip package and the connector. Multiple cables can be used to provide a number of differentially coupled channels.
