Filter Combiners

SDP Filter Combiners are designed for co-siting purposes which enable sharing the same feeder cable for multiple frequency bands. The units can be used as a combiner near the BTS or as a splitter near the antenna. The units are designed to sustain the highest environmental and reliability requirements.

Features:

  • Dual, triple or quad-band combiner
  • Dual or single unit for XPol antennas
  • Built-in lightning protection and DC by-pass
  • Indoor and outdoor applications
  • Different technologies such as Dielectric Resonator (DR), Combline, Suspended Substrate, and Stripline
  • Balanced combiners based on integration DR/coaxial and hybrid couplers

Typical performances

  • Insertion Loss < 0.3 dB
  • VSWR 1.25
  • Impedance 50 Ω
  • 7-16 connectors
  • IP 66
