18GHz low loss cable allow for 75% lower phase shift

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

Fairview Microwave’s new 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, Fairview’s new low loss cables allow for a 75% lower phase shift due to the precise construction of these cables. This cable configuration offers attenuation levels 20 to 35% lower than comparable mil-spec cables.

Fairview’s new 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 from Fairview 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.

“Our new low loss cable assemblies, built with LL335i and LL142 coax, are a valuable addition to our ever-expanding line of high performance RF test cables”, says Greg Arnold, Technical Sales Manager at Fairview Microwave.  “These low loss, phase stable, double shielded cables offer engineers and technicians improved performance over standard RG-type cables in a rugged design, ideal for heavy-use test environments where repeatability and stability are paramount.”
