LTE high-speed twinaxial cables—100Ω parallel and twisted pair

LTE

low-density, air-expanded PTFE dielectric gives

these cables very fast transmission speeds and low

loss in a small size, along with exceptional ﬂexibility.

These cables are just some examples of the

performance levels provided by LTE dielectric—

many other conﬁgurations are also available.

Performance:

Temperature rating:

919 series: 90˚ C.

TC-746: 150˚ C.

Velocity of propagation:

83%.

Time delay:

1.23 ns / foot nominal.

See page 3 for more information on LTE dielectric.

Construction Details

Center Conductor:

919 series: Solid silver-plated copper.

TC-746: Stranded silver-plated high-

strength copper alloy.

Primary Insulation:

LTE (extruded expanded

low-density PTFE).

Drain Wire:

919 series: Same as conductor.

TC-746: None.

Shield:

919 series: Aluminum/polyethylene/aluminum tape.

TC-746: AWG 38 nickel-plated copper,

95% coverage.

Jacket:

919 series: Extruded PVC, white;

TC-746: Extruded ETFE, white.

Options:

Other jacket colors; other conductor materials,

gauges and / or stranding; other impedances;

other transmission speeds.
