Coax Feeders, Jumpers & Connectors


Coax Feeders - Complete Range of Products

Rosenberger offers a complete range of 50Ω coaxial cables from 1/4" to 1 5/8". The feeders provide best in-class electrical and mechanical performance:

  • Low attenuation
  • Low VSWR/RL
  • CPR-rated
  • Complete EMI shielding to minimize system interference
  • Outstanding PIM performance
  • High-power rating

The cable construction is similar for all cable sizes: Inner conductor, foam dielectric, outer conductor and outer jacket. The cables are available as standard with either a PE jacket for outdoor installations or in a flame retardant and halogen-free version to comply with indoor requirements for health and safety, IEC 60332 and CPR-EN 50575.


Coax Jumpers - Superior Performance up to 6 GHz

Rosenberger coaxial jumpers have been designed using the many years of experience gained by Rosenberger engineers in this field. The unique knowledge of designing and manufacturing world-leading PIM testing equipment is directly reflected in the jumpers.

Rosenberger jumpers have the industry-best PIM levels: -117 dBm / -160 dBc @ 2 x 20 W (typ. -120 dBm / -163 dBc @ 2 x 20 W). These excellent levels are guaranteed for every assembly that leaves the Rosenberger production facility.

Traceability - Rosenberger jumpers are individually tested for return loss and PIM. Test data can be retrieved in 3 ways:

  • By scanning in the data matrix code on the jumper packaging
  • By scanning in the bar code on the jumper itself
  • By entering the serial number on
