3/8" CELLFLEX® Low-Loss Foam-Dielectric Coaxial Cable

Rev : P3 | Rev date : 15 Jan 2024

CELLFLEX® 3/8" low loss flexible cable support CBRS, C-Band and LAA up to 6GHz

FEATURES / BENEFITS

  • Ultra Low Attenuation

The reduced attenuation of CELLFLEX® coaxial cable results in extremly efficient signal transfer in your RF system, especially at high frequencies. 

  • Complete Shielding

The solid outer conductor of CELLFLEX® coaxial cable creates a continuous RFI/EMI shield that minimizes system interference. 

  • Low VSWR

Special low VSWR versions of CELLFLEX® coaxial cables contribute to low system noise. 

  • Outstanding Intermodulation Performance

CELLFLEX® coaxial cable's solid inner and outer conductors virtually eliminate intermods. Intermodulation performance is also confirmed with state-of-the-art equipment at the RFS Technologies factory. 

  • High Power Rating

Due to their low attenuation, outstanding heat transfer properties and temperature stabilized dielectric materials, CELLFLEX® cable provides safe long term operating life at high transmit power levels. 

  • Wide Range of Application

Typical areas of application are: feedlines for broadcast and terrestrial microwave antennas, wireless cellular, PCS and ESMR base stations, cabling of antenna arrays, and radio equipment interconnects
