a bank of adjusters disposed between and in communication with at least the input hybrid matrix and the output hybrid matrix; and

a driver circuit connected to each adjuster in the bank of adjusters, the driver circuit being configured to command each adjuster to modify communication signals, passing through the matrix power amplifier, at time division multiple access rates so that outputs of the bank of high power amplifiers are re-routed at the time division multiple access rates between predetermined antenna beams based on a modification to a communication signal.

2. The communication system of claim 1 , wherein there is an adjuster corresponding to each high power amplifier.

3. The communication system of claim 2 , wherein the adjuster is disposed upstream from the corresponding high power amplifier.

5. The communication system of claim 1 , wherein each adjuster is configured to change a phase of the communication signals in a re-mapping of each input of the input hybrid matrix to a predetermined output of the output hybrid matrix.

6. The communication system of claim 1 , further comprising at least one downlink antenna beam where each output of the output hybrid matrix is coupled to a respective downlink antenna beam.

7. The communication system of claim 1 , wherein the bank of adjusters is configured to cause a selectable remapping of at least one output of the output hybrid matrix with respect to at least one input of the input hybrid matrix at time divisional multiple access rates and free from high power output switching.

8. The communication system of claim 7 , wherein each high power amplifier of the bank of high power amplifiers operates simultaneously.

9. The communication system of claim 1 , wherein the communication signals are radio frequency signals or optical signals.

10. A matrix power amplifier comprising:

14. The matrix power amplifier of claim 10 , wherein each adjuster is configured to change a phase of the communication signals in a re-mapping of each input of the input hybrid matrix to a predetermined output of the output hybrid matrix.

15. The matrix power amplifier of claim 10 , wherein the bank of adjusters is configured to cause a selectable remapping of at least one output of the output hybrid matrix with respect to at least one input of the input hybrid matrix at time divisional multiple access rates and free from high power output switching.

16. A method of communication comprising:
inputting a communication signal to an input hybrid matrix of a matrix power amplifier; and
selectively re-routing, at time division multiple access rates, the communication signal to a predetermined output of an output hybrid matrix of the matrix power amplifier by modifying the communication signal at the time division multiple access rates.

17. The method of claim 16 , wherein the communication signal is modified prior to the communication signal entering a high power amplifier of the matrix power amplifier.
