DIGITAL UPCONVERSION FOR MULTI-BAND MULTI-ORDER POWER AMPLIFIERS

摘要

The present disclosure relates to digital up-conversion for a multi-band Multi-Order Power Amplifier (MOPA) that enables precise and accurate control of gain, phase, and delay of multi-band split signals input to the multi-band MOPA. In general, a multi-band MOPA is configured to amplify a multi-band signal that is split across a number, N, of inputs of the multi-band MOPA as a number, N, of multi-band split signals, where N is an order of the multi-band MOPA and is greater than or equal to 2. A digital upconversion system for the multi-band MOPA is configured to independently control a gain, phase, and delay for each of a number, M, of frequency bands of the multi-band signal for each of at least N-1, and preferably all, of the multi-band split signals.

主权项

1. A system comprising:
a multi-band multi-order power amplifier configured to amplify a multi-band signal split across a plurality of inputs of the multi-band multi-order power amplifier as a plurality of multi-band split signals, the plurality of inputs comprising a different input for each of N orders of the multi-band multi-order power amplifier where N is greater than or equal to 2; and a digital upconversion system for the multi-band multi-order power amplifier that is configured to control a gain, phase, and delay for each of M frequency bands of the multi-band signal for each of at least N-1 of the plurality of multi-band split signals independently from the gains, phases, and delays of other multi-band split signals.
