Transcript of "Rfconnext High Speed Flex 20 Ghz Measured Data"

  1. 1. RFCONNEXT: Comparing High Speed Flex Performance using PMTL™ and Microstrip up to 20GHz Single Ended, and Differential, Insertion Loss, Return Loss, FEXT, NEXT Crosstalk, and TDR impedance Profiles Advancing the High Speed Interconnect Ecosystem™… Jamal S. Izadian, Ph.D. jsi@rfconnext.com 408-981-3700 September 24, 2009 www.rfconnext.com
  2. 2. Notes • All Measured Data includes the two SMA connectors, unless otherwise stated • The Performance of the Flex Cables Seem to be limited by the Connectors • It is estimated that these PMTL™uFlex operate to 26.5GHz Copyright 2008 RFCONNEXT, Inc.

  20. 20. 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 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 Copyright 2008 RFCONNEXT, Inc.
