METHOD FOR ENVELOPE TRACKING MULTIPLE TRANSMISSIONS THROUGH A SINGLE POWER AMPLIFIER |
| 摘要 |
In one example, a method is performed on an integrated circuit, for generating a composite envelope reference voltage for a plurality of transmit signals. The method includes, generating a composite baseband signal from a plurality of baseband signals, wherein the plurality of baseband signals represent a corresponding plurality of different transmit signals. The method also includes calculating a composite envelope signal for the composite baseband signal, and generating a composite envelope reference voltage from the composite envelope signal for use in powering a single power amplifier as the power amplifier transmits the plurality of different transmit signals. |

1. A method, performed on an integrated circuit, for generating a composite envelope reference voltage for a plurality of transmit signals, the method comprising:
generating a composite baseband signal from a plurality of baseband signals that represent a corresponding plurality of different transmit signals; calculating a composite envelope signal for the composite baseband signal; and generating a composite envelope reference voltage from the composite envelope signal for use in powering a single power amplifier as the power amplifier transmits the plurality of different transmit signals. |
