Multicouplers
COM-TECH proprietary and complete solutions, offering practical and efficient components to drive and combine several Power Amplifiers, providing the maximum possible overall efficiency of the Transmitter.

Techniques
Two different systems, with different techniques, are available:

  • Quadrature Multicoupler System (MC Series Multicouplers and QS Series Splitters)
  • Progressive Multicoupler System (MH Series Multicouplers and SP Series Splitters)

Components
Both systems include two main components:

  • Multicoupler: sums the power of the Amplifiers, and can be conveniently plugged-in at the back of the Power Amplifiers themselves, thanks to the Unified Connector Spacing, which enables connectors to be spaced at a multiple of Rack Units (2U, 3U, 3,5U…). In case of 2-way combination a simple Hybrid Coupler is used.
  • Splitter: divides the power into the correct number of outputs, driving the Power Amplifiers with accurately balanced amplitudes and correct phases in order to be subsequently be re-combined by the Multicoupler with the highest possible efficiency

Quadrature Multicoupler System
This cost-effective system makes use of Quadrature Couplers and Splitters:

  • 3, 4 and 5-way combinations available (2-way with a Hybrid Coupler)
  • 3U and 3.5U Unified Connector Spacing
  • Direct plug-in into Power Amplifiers (Quick Plug Connectors available)
  • Cost effective solution
  • Low and medium power
  • Ideal for Air-Cooled transmitters

MC Series Quadrature Multicouplers

  • High Efficiency (Typical 99%, corresponding to 0.04 dB overall Insertion Loss)
  • High Port Isolation (> 30 dB), allowing partial operation and hot replacement of amplifiers
  • Phase Compensated Design (3-way and 5-way)

QS Series Quadrature Splitters

  • Outputs with proper phase and balanced amplitude levels, providing optimum amplifier performance
  • 2, 4, and 8-way Splitters available; odd-numbered Splitters obtained by the even-numbered Splitters terminating the unused outputs

Progressive Multicoupler System
This innovative system makes use of Progressive Couplers and Splitters:

  • 3, 4 and 5-way combinations available (other combinations available on request)
  • 2U and 3U Unified Connector Spacing
  • Direct plug-in into Power Amplifiers (Quick Plug Connectors available)
  • Integrated Liquid Cooled load (Option)
  • High power
  • Ideal for Liquid-Cooled transmitters

MH Series Progressive Multicouplers

  • High Efficiency (Typical 99%, corresponding to 0.04 dB overall Insertion Loss)
  • High Port Isolation (> 30 dB), allowing partial operation and hot replacement of amplifiers

PS Series Progressive Splitters

  • Outputs with proper phase and equalized amplitude levels, providing optimum amplifier performance
  • 3, 4 and 5-way Splitters available
