SDP combiners are used to combine wireless carriers or signals with minimal interaction and PIM level, essentially providing lossless combining. An N by N combiner is a network having N input and N output ports in which a signal applied to one of the input ports is equally divided into output ports.

Key Features

  • High-in band isolation, and low VSWR
  • Low PIM
  • Low insertion loss and broadband
  • High Power Rating, up to 100 W per input
  • Flexible number of inputs and outputs
  • Indoor and outdoor applications

*The Hybrid Combiner is a network that allows the combination of signals without those signals interacting, however close they are in frequency. If not all the outputs are used, the unused output must be terminated with low PIM terminations (not included, see SDP Low IMD terminations) with suitable PIM requirement and power level. The rating for this load must be at least half the sum of the power of all inputs. The 2×2, 3×3 and 4×4 product is available with 2W or a 10W-integrated load. If guaranteed low PIM is a requirement, then a low PIM termination must be either used, externally or integrated.
