Abstract
A circulator for radio frequency is provided. The circulator may include a ferrite stripline assembly, which includes a first ferrite layer, a second ferrite layer over the first ferrite layer, and a junction circuit between the first ferrite layer and the second ferrite layer. The circulator may also include a magnet over the second ferrite layer for providing magnetic bias.
Claims21
A circulator for radio frequency, the circulator comprising:
- a ferrite stripline assembly comprising:
- a first ferrite layer;
- a second ferrite layer disposed over a first side of the first ferrite layer;
- a junction circuit between the first ferrite layer and the second ferrite layer, wherein the junction circuit comprises a first circuit formed on the first side of the first ferrite layer, a second circuit formed on a second side of the second ferrite layer;
- a first ground layer contacting the first ferrite layer and opposite to the junction circuit;
- a magnet over a first side of the second ferrite layer for providing magnetic bias;
- a second ground layer between the second ferrite layer and the magnet, the second ground layer opposite to the junction circuit;
- and
- one or more perimeter grounds located on a respective perimeter of the first ferrite layer and the second ferrite layer, wherein the one or more perimeter grounds are integrated with the first ground layer and the second ground layer.
A circulator for radio frequency, the circulator comprising:
- a ferrite stripline assembly comprising:
- a first ferrite layer;
- a second ferrite layer disposed over the first ferrite layer;
- a junction circuit between the first ferrite layer and the second ferrite layer;
- a metal seed layer over all surfaces of each of the first ferrite layer and the second ferrite layer;
- and
- a magnet over the second ferrite layer for providing magnetic bias.
A circulator for radio frequency, the circulator comprising:
- a ferrite stripline assembly comprising:
- a first ferrite layer;
- a second ferrite layer disposed over the first ferrite layer, wherein the first and second ferrite layers are attached by an intermetallic bond or a paste;
- a junction circuit between the first ferrite layer and the second ferrite layer;
- and
- a magnet over the second ferrite layer for providing magnetic bias.
