Abstract
An above resonance circulator/isolator and method for manufacturing the same is described. In one implementation, the above resonance circulator/isolator includes a magnet, a spacer, a single ferrite element, a center conductor and a pole piece. The center conductor is sandwiched between the magnet and the single ferrite element with the spacer interposed between the magnet and the center conductor. The pole piece is coupled to the single ferrite element, such that the single ferrite element is sandwiched between the center conductor and the pole piece. Magnetic shielding is not necessary in particular implementations.
Claims12
An above resonance isolator/circulator, comprising:
- a magnet;
- a spacer;
- a single ferrite element;
- a center conductor sandwiched between the magnet and the single ferrite element with the spacer interposed between the magnet and the center conductor;
- and
- a pole piece coupled to the single ferrite element, such that the single ferrite element is sandwiched between the center conductor and the pole piece;
- wherein no immediate magnetic shielding is used to encase the magnet, the spacer, the single ferrite element, the center conductor, and the pole piece.
An above resonance isolator/circulator, comprising:
- a magnet;
- a spacer positioned directly underneath the magnet;
- a center conductor positioned directly underneath the spacer;
- a single ferrite element positioned directly underneath the spacer;
- and
- a ground plane positioned underneath the single ferrite element, wherein no metal elements are interposed between adjacent ones of the magnet, the spacer, the single ferrite element, and the center conductors;
- wherein no immediate magnetic shielding is used to encase the magnet, the spacer, the single ferrite element, the center conductor, and the ground plane.
