LTE

is a patented low-density, air-expanded PTFE

dielectric which provides reduced weight and

increased velocity of propagation (up to 85%).

LTE dielectric also exhibits low loss and stable

performance throughout its temperature range.

These cables are ideal replacements for MIL-C-17

cables in demanding applications such as aerospace

and high-reliability commercial systems.

875-892 is a replacement for RG-179 (M17/94).

900-142 is a replacement for RG-142 (M17/60, /158).

900-316 is a replacement for RG-316 (M17/113, /172).

900-393 is a replacement for RG-393 (M17/127, /174).

Performance:

Temperature rating:

200˚ C.

Impedance:

875-892: 75Ω nominal.

All others: 50Ω nominal.

See page 3 for more information on LTE dielectric.

Electrical Performance

Dimensions and Weights

Dimensions in inches (mm). Weights in pounds/1000 feet (Kg/1000 M). All values are nominal unless otherwise indicated.

SPC:

Silver-plated copper. SPCW: Silver-plated copper-covered steel (copperweld). SPCA: Silver-plated high-strength copper (alloy 135).

Outer Shield:

Silver-plated copper braid, 95%

nominal coverage. Can be provided with

optional shield types such as ﬂat braid, tape

composites, or combinations.

Jacket:

Extruded FEP.

All values are nominal unless otherwise indicated.
