Abstract

A magnet-less multi-port ring combiner comprises a set of ports extending from the circumference of the magnet-less multi-port ring combiner. The set of ports are positioned at ¼ increments around the circumference of the magnet-less multi-port ring combiner. The set of ports comprise a first input port configured to receive a first input signal and a second input port configured to receive a second input signal, wherein the first input signal is 180° out-of-phase with the second input signal. The N-way magnet-less multi-port combiner comprises more than four ports.

First claim

What is claimed is:

1. A magnet-less multi-port ring combiner comprising:
a set of ports extending from a single continuous trace of the magnet-less multi-port ring combiner, wherein the set of ports are positioned at λ/4 increments around an electrically continuous circumference of the magnet-less multi-port ring combiner; and
the set of ports comprise a first input port configured to receive a first input signal and a second input port configured to receive a second input signal, wherein the first input signal is 180° out-of-phase with the second input signal, wherein:
the set of ports comprise more than four ports, and
relative to each input port, all other input ports are at 180° out-of-phase signal nulls, relative to each output port, all other output ports are at 180° out-of-phase signal nulls.

2. The multi-port ring combiner of claim 1 , wherein the set of ports comprise six ports.

3. The multi-port ring combiner of claim 1 , wherein a first group of input ports share a common relative phase difference between output ports.

4. The multi-port ring combiner of claim 1 , wherein any two ports are connected by two discrete and non-overlapping paths.

5. The multi-port ring combiner of claim 1 , wherein the combiner comprises a shape other than circular.

6. The multi-port ring combiner of claim 1 , wherein input ports selected from the set of ports are spaced at multiples of λ/2 from each other.

7. The multi-port ring combiner of claim 1 , wherein the magnet-less multi-port ring combiner consists of passive components.

8. A magnet-less multi-port combiner comprising:
a set of ports extending from a single continuous trace of the magnet-less multi-port combiner, wherein the set of ports are positioned at λ/4 increments around the single continuous trace of the magnet-less multi-port combiner;
the set of ports comprise a first group of input ports that are spaced around the single continuous trace at multiples of λ/2 from each other; and
wherein:
the magnet-less multi-port combiner consists of passive components,
the set of ports comprise more than four ports, and
relative to each input port, all other input ports are at 180° out-of-phase signal nulls, relative to each output port, all other output ports are at 180° out-of-phase signal nulls.

9. The multi-port combiner of claim 8 , wherein the set of ports comprise six ports.

10. The multi-port combiner of claim 8 , wherein the first group of input ports share a common relative phase difference between output ports.

11. The multi-port combiner of claim 8 , wherein any two ports are connected by two discrete and non-overlapping paths.

12. The multi-port combiner of claim 8 , wherein the combiner comprises a shape other than circular.

13. The multi-port combiner of claim 8 , wherein the combiner comprises a circular shape.

14. A magnet-less multi-port ring combiner comprising:
a set of ports extending from a single continuous trace of the magnet-less multi-port ring combiner, wherein the set of ports are positioned at λ/4 increments around the an electrically continuous circumference of the magnet-less multi-port ring combiner; and
wherein:
the set of ports comprise more than four ports,
relative to each input port, all other input ports are at 180° out-of-phase signal nulls, relative to each output port, all other output ports are at 180° out-of-phase signal nulls, and
any two ports are connected by two discrete and non-overlapping paths.
