Ka band feed systems

Ka Band feed system, 2 Port

The 2 port ka band feed system comes in two different versions for different operational bands. The system includes high-pass (HP) filter in TX port as well as a band stop (BS) filter in the RX port. The system is comprised of Ortho-mode Transducer (OMT), HP filter, BS filter, Polarizer.

  • Receive Reject Filtering
  • Transmit Reject Filtering
  • Orthomode Transcducer
  • Polarizer

Ka Band feed system, 4 Port

RQT-KKa-4port-unit operates at both K and Ka band for satellite communication transmit and receive operation.  This feed unit includes all waveguide components required for full 4 port operation in one full robust unit:

  • Receive Reject Filtering
  • Transmit Reject Filtering
  • Orthomode Transcducer
  • Polarizer

This compact and robust construction has been one of our most popular feed designs for the satellite communication industry.
