L-com Develops Durable Low-loss Cables For Test Environments

L-Com LL Series

 April 7, 2020

L-Com Low-loss Cables

L-com has launched a new series of flexible 18 GHz LL142 and LL335i low-loss cables. These new cable assemblies are terminated with durable stainless steel connectors and are well suited for test environments where a rugged, phase stable cable assembly is required.

L-com’s new low-loss cables utilize a 0.195 & 0.300 inch diameter coax with an expanded dielectric which results in 80% and 83% Velocity of Propagation (VoP) performance up to 18 GHz. These coaxial cable assemblies feature LL142 and LL335i coax cable, which operates at higher power with improved phase stability. The triple shielded flexible coax provides excellent shielding effectiveness greater than 95 dB and VSWR of less than 1.35:1. A heavy duty boot and FEP jacket improve strain relief and allow for a minimum bend radius of .945 and 1.5 inches which adds to the durability of these cable assemblies.

L-com’s new line of LL142 and LL335i test cables are offered with male-straight and right-angle versions of Type-N, SMA, and TNC connectors as well as female bulkhead versions for each connector series. These new cables can be ordered in custom lengths and are also available in standard lengths from 1 Ft to 10 Ft. Each assembly is 100% continuity, Hi-Pot and RF tested prior to shipment.

“These new cables offer our customers a high performance solution when requiring a low-loss cable assembly. The smaller diameter of these new 18 GHz coax cables provides a tighter bend radius while offering low loss and higher power when compared to solid dielectric cables,” said Steve Ellis, Product Line Manager.

L-com’s new 18 GHz, LL142 and LL335i coaxial cables are all in-stock and available for immediate shipment.
