Abstract

One or more embodiments of the present invention describe an apparatus and method to combine unequal powers. The apparatus includes a first input port, a second input port, and a combiner. The first input port is operably connected to a first power amplifier and is configured to receive a first power from the first power amplifier. The second input port is operably connected to a second power amplifier and is configured to receive a second power from the second power amplifier. The combiner is configured to simultaneously receive the first power from the first input port and the second power from the second input port. The combiner is also configured to combine the first power and second power to produce a maximized power. The first power and second power are unequal.

First claim

We claim:

1. An apparatus, comprising:
an input port configured to receive input power from a high frequency Ka-band or higher power amplifier;
first and second output ports configured to output power;
a power divider with no differential phase shifter and no septum polarizer configured to divide the received input power from the input port between the first and the second output ports; and
an isolated port configured to receive negligible or no power from the divider, wherein the isolated port is grounded or match terminated; and
wherein the power at the first and the second output ports are unequal and further wherein the divider can divide with both integral and non-integral power ratios including any arbitrary ratio of unequal output powers.

2. The apparatus of claim 1 , wherein:
the first output port is operably connected to a second divider and the second output port is operably connected to a third divider;
the second divider and the third divider are configured to simultaneously receive power;
the second divider is configured to divide the power from the input port and produce a third and a fourth output power;
the third divider is configured to divide the power from the input port and produce a fifth and a sixth output power; and
the third and fourth output powers are unequal and the fifth and sixth output powers are unequal.

3. The apparatus of claim 2 , wherein the third and fourth output powers are outputted from the third and fourth output ports to loads or to a fourth and a fifth divider or antennas; and the fifth and sixth output powers are outputted from the fifth and sixth output ports to loads or to a sixth and a seventh divider or antennas.

4. The apparatus of claim 2 , wherein a second isolated port and a third isolated port are configured to receive negligible power or no power from the second and third dividers, wherein the second and third isolated ports are grounded or match terminated.

5. The apparatus of claim 1 , wherein the first and the second output ports are operably connected to loads or antennas.

6. A method, comprising:
receiving at an input port, power from a power amplifier at Ka-band or higher frequency;
configuring a first output port and a second output port to output powers;
configuring a power divider with no differential phase shifter and no septum polarizer to divide the received input power between the first and the second output ports;
receiving, at an isolated port, negligible or no power from the divider; and
wherein the first output power and the second output power are unequal and further wherein the divider can divide both integral and non-integral power ratios including any arbitrary ratio of unequal output power.

7. The method of claim 6 , further comprising
outputting the divided powers from the first divider to a second divider and a third divider, via output ports;
simultaneously receiving the divided powers at inputs of the second and third dividers; and
dividing, at the second divider and producing a third and fourth output powers and dividing at the third divider and producing a fifth and sixth output powers,
wherein the third and fourth output powers are unequal and the fifth and sixth output powers are unequal.

8. The method of claim 7 , further comprising:
outputting the third and the fourth output powers from the second divider to loads or additional power dividers or antennas; and
outputting the fifth and the sixth output powers from the third divider to loads or additional power dividers or antennas.

9. The method of claim 7 , further comprising:
receiving, at the second and third isolated ports, negligible power or no power from the second and third dividers.

10. The method of claim 6 , further comprising:
outputting the divided power from the divider to a load, via output ports.

11. An apparatus, comprising:
a divider, with no differential phase shifter and no septum polarizer, comprising an input port, two output ports, and an isolated port,
wherein the divider is configured to receive a high frequency Ka-band or higher power from a power amplifier, via the input port, and divide the input power into two output powers and make them available via the two output ports, wherein the divider can divide both integral and non-integral power ratios including any arbitrary ratio of unequal output power; and
wherein the divider is further configured to output the divided powers to a second divider and a third divider, via the output ports of the divider.

12. The apparatus of claim 11 , wherein the second and third dividers are configured to simultaneously receive the divided powers from the divider, via input ports of the second and the third dividers, wherein divided powers at outputs of the second and third dividers are unequal.

13. The apparatus of claim 12 , wherein the second divider and the third divider are further configured to divide the power into both integral and non-integral power ratios including any arbitrary ratio of unequal output power.

14. The apparatus of claim 12 , wherein the second and third dividers are further configured to output the divided powers to an additional divider or a load via output ports of the second and third dividers, and output negligible or no power via isolated ports of the second and third dividers.

15. The apparatus of claim 11 , wherein the divider is further configured to output negligible or no power via the isolated port of the divider.

16. The apparatus of claim 11 , wherein the divider is further configured to output the divided powers to loads, via the output ports of the divider.
