Cable assemblies offer low loss to 18 GHz

Fairview Microwave has introduced a line of low loss test cables using LL335i and LL142 coax. Rated to 18 GHz, these low loss cable assemblies are ideal for test environments where a rugged, phase stable cable assembly is required.

The company's LL335i and LL142 cables allow for higher power transmission because the resulting higher temperatures do not have a negative effect on the cable due to the thermal stability of the PTFE tape dielectric. Where phase stability requirements are critical, these low loss cables allow for a 75% lower phase shift due to the precise construction of the cables. This cable configuration offers attenuation levels 20 to 35% lower than comparable mil-spec cables.

The RF cable assemblies come equipped with a choice of stainless steel TNC, SMA and N-Type connectors and a heavy duty booting to improve strain relief. These low loss test cables are made with LL335i or LL142 coax, which operate at higher power with better phase stability from traditional cables with solid dielectrics. A double shielded flexible coax provides shielding greater than 95 dB and VSWR of less than 1.35:1.
