Abstract
An equalizer that couples a dual-mode dielectric resonator to a planar transmission line, creating an all-pass network. Coupling is achieved using circular polarization of the electromagnetic field in the dielectric resonator. The all-pass, non-reciprocal network is realized by the use of circular polarized energy and an offset cross shaped, through transmission line.
Claims9
A dielectric resonator equalizer comprising:
- a cavity;
- first and second orthogonal tuning screws that extend through a wall of the cavity into the interior thereof;
- first and second opposed mode decoupling screws that extend through the wall of the cavity into the interior thereof;
- a dual-mode dielectric resonator disposed in the cavity;
- input and output connectors disposed at opposite ends of the cavity;
- a transmission line comprising an offset cross member disposed in the cavity and coupled to the input and output connectors;
- an aperture coupling disposed in the cavity between the transmission line and the dual-mode dielectric resonator.
