Our standard feed combiners can be found as one key part of our feed systems. MIRAD feed combiners are designed, manufactured and tested in our facility with Swiss precission in all areas and under the strict controll of our quality management. The feed combiner configurations are available from simple 2-port linear polarized systems up to polarization switchable 6-port devices including TE21 monopulse tracking. Complexe multiband systems with special requirenments for any application can be requested to our sales team. Our highly skilled engineering team will serve you a corresponding solution approach. If high power applications, low PIM level specification or polarization switching, MIRAD provides you modular solutions for all needs. 

Feed Combiner Components

4-port Ka-band feed combiner with forced cooling
All feed combiners are also available as stand-alone units and can be adapted to the customers feed horn. We also offer individual feed horn design and the corresponding antenna performance calculations to optimize your system transmission behaviour. 
Adjacent picture illustrates a MIRAD standard circular polarized, 4-port Ka-band combiner with forced air cooling to provide high power transmission. 
  • Blue: Taper, interface to the circular waveguide or horn
  • Green: Orthomode transducer (OMT), separation of polarization
  • Orange: Diplexers, separation of transmit and receive frequency bands
  • Turquoise: Hybrid couplers, recombination of orthogonal signals to produce circularity

Any component of the feed combiner is available as single component as well. However, in order to get best possible performance a single source solution is recommended.

MIRAD Standard Feed Combiners


    • 2-port, 4-port and 6-port
    • Linear or circular polarization (polarization switch) 
    • TE21 monopuls tracking coupler
    • Rotatable polarization units for linear polarized feeds
    • Flexible designs (straight or folded)
    • low PIM level verification
The adjacent pictures illustrate some of MIRADs standard feed combiner units.

Please note that the feed combiners are available in a broad range of different types and configurations. Just contact us with your specific requirements and we will provide you with all necessary details immediately. If a standard feed combiner does not meet your specification, our engineering is at your service to design a customized solution.
