March 12, 2014. Fairview Microwave Inc. a supplier of on-demand microwave and RF products, has introduced a new line of low-loss test cables using LL335i and LL142 coax. Rated to 18 GHz, these new-low loss cable assemblies are suitable 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,” said 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.”
