Multi-Output Coupler

  • Octave Bands Within 0.5 to 20 GHz
  • Any number of outputs.
  • Different bands within the same unit.
  • Different coupling values within same unit.
  • Coupling values: 8 – 30 dB
  • In-series configuration.
  • Combination of forward and reverse couplers.
Short Lead Time
  • Designed and delivered typically within 12 weeks.
Advantages vs. Separate Units
  • Compact size.
  • Minimize loss and reflections.
  • Eliminates the need for additional power divider when multiplexing.

Case Study: Quad 8.5 dB Coupler
The customer required four 8.5 dB couplers at four different frequency bands.  Each coupler was required to be electrically isolated from the others and feed separate low noise amplifiers (LNAs) tuned to different bands.

Traditional approach would require a single coupler fed into a 4-way splitter, followed by bandpass filters.  This implementation would have added an additional ~7 dB of loss, which would have negated the benefit of the low noise amplifiers.

Werbel Microwave works B2B. Company information is required.
As splitter into load VSWR 1.2:1 max.
Describe the number of outputs and frequency at each output. Each output can be a different frequency range, if needed.
