Cannot one put intermediate buffers along a transmission line to reduce the reflections and effectively increasing the bandwidth? If there is a certain amount of ringing involved in a line of length L then putting a buffer half way should approximately double the bandwidth? Assuming off course the buffers have the bandwidth. Is this a good way to solve the problems in some cases? I have a trace on a pcb that is approximately 18 inches long and I have a cable that connects to it that is approximately 2ft long. I do terminate the line the pcb but I'm running up against transmission line effects and I imagine if I put a buffer at the boundary between the pcb and cable it would solve my problem?
But I was thinking, hypothetically, if one could divide a transmission line into N pieces with each piece having it's own buffer and termination then one could theoretically get extremely high speeds? Assuming the buffer and termination have infinite bandwidth then bandwidth will be proportional to N? The extreme case would be to someone have a continuous buffer solution. Also the more pieces the less you need termination since each piece is smaller. So if one could find a very cheap way to insert buffers into copper one would not need termination and could have pretty good bandwidth?
