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 OEMs.
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 its 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.
