Notes
• All Measured Data includes the two SMA connectors, unless otherwise stated
• The Performance of the Flex Cables Seem to be limited by the Connectorsto be limited by the Connectors
• It is estimated that these PMTL™uFlexoperate to 26.5GHz

Observations
• PMTL™uFlex, outperformers MS Flex• The PMTL™ uFlex is highly scalable
– Can be scaled to micron dimension for space and trace on low end– Can be scaled to mm, dimension on high end
• Many New interconnects are possible– High Speed Ribbon Cables, Jumpers, Bus– High Speed Ribbon Cables, Jumpers, Bus– High Speed Connectors and Termination
• Can be fabricated using low cost felx, rigid, or Rigid-Flex materials using traditional PCB processes
• Can be printed in long length, side by side, using new R2R process• Can be used as alternative to coaxial cables and twisted pairs, at
lower cost, with similar performance, using only 10% of resources
