TFlex employs a thin helical wrap of silver plated copper tape and overall braid sized such that standard solder-on connectors can be used.

TFlex was developed 10 years ago and have been widely adopted by the commercial and military OEM’s.

Some of the key characteristics of TFlex are:

  • Passive Intermod – typically > -150dBc (2x 20 watt carriers)
  • Shielding Effectiveness – comparable to standard semirigid and like semirigid is beyond measurable limits.
  • Small/Lightweight – same size but lighter weight than standard CL semirigid coax.
  • Phase Stable – the helical tape outer conductor minimizes electrical length change with temperature to yield substantial improvement over equivalent size flexible cables.
  • Low Loss – can achieve loss comparable to standard CL semirigid coax.
  • Attenuation Stability – silver plated outer conductor prevents oxidation of the conductors thereby minimizing attenuation change vs time.
  • Power Handling – comparable to standard CL semirigid.
  • Corrosion Resistance – jacketing of the cable with FEP provides excellent protection when cable is deployed in a corrosive environment.
  • Formability – the flexible nature of TFlex eliminates the need for hand or precision machine bending. TFlex is preterminated in it’s approximate desired length and just ‘plugged in’ using the most convenient/desirable routing.
  • Connectors (solder-on) – are available from a variety of sources to fit standard semirigid coax and TFlex.
