Abstract
Provided herein are various enhancements for waveguide structures used in radio frequency feed components. In one example, an apparatus includes a septum polarizer having first feed ports and a common port, a high-pass filter coupled to the common port of the septum polarizer, and a multi-port orthomode transducer (OMT) coupled to the high-pass filter and providing an antenna port. The apparatus also includes hybrid couplers coupled to low-pass filters fed from the multi-port OMT, and magic tee elements cross-coupled to the hybrid couplers and providing second feed ports.
