Abstract
A hybrid circulator includes an isolator and an orthomode transducer coupled to the isolator. The hybrid circulator achieves high performance in the microwave and millimeter-wave (MMW) frequency range.
Claims18
A hybrid circulator comprising:
- at least three hybrid circulator ports;
- a Faraday rotator including a cylindrical ferrite rod surrounded by a radio frequency (RF) absorbing material and coupled to a dual-moded waveguide by a first dielectric transition element attached to one end of the cylindrical ferrite rod and coupled to a single mode rectangular waveguide by a second dielectric transition element attached to the other end of the cylindrical ferrite rod;
- and
- an orthomode transducer coupled to the Faraday rotator,
- wherein the Faraday rotator and the orthomode transducer are coupled by the dual-moded waveguide, and
- wherein the hybrid circulator is non-reciprocal and directs a microwave signal or a radio frequency signal entering one of the at least three hybrid circulator ports to exit through another of the three hybrid circulator ports directly after the one hybrid circulator port it entered.
