Structure and Composition

Integrated with an E-plane tee and H-plane tee, its core transmission unit adopts a double-ridged waveguide design. Two symmetrical protruding metal ridges are arranged inward on the broad walls of the rectangular waveguide cavity.

With optimized double-ridged gradual transition profiles and embedded metal matching components, it achieves excellent broadband performance, supporting an operating frequency range of more than one octave. The compact integrated structure guarantees high structural stability and convenient system integration.

Working Principle

  • Odd Symmetric Wave

    When signals are fed into one collinear port in odd symmetric mode, power is equally distributed to two balanced arms with reverse electric field phases. No unwanted power coupling occurs at the opposite collinear port.

  • Even Symmetric Wave

    For signals injected from the other collinear port in even symmetric mode, energy is evenly transmitted to two balanced arms with identical electric field directions, while maintaining complete isolation from the first collinear port.

Port Isolation

Relying on the propagation characteristics of odd-mode and even-mode electromagnetic waves inside the double-ridged cavity, independent transmission paths are formed for different excitation ports. It realizes high isolation between non-corresponding ports and accurate energy partitioning, avoiding crosstalk and signal interference.
