DIGITAL PAYLOAD WITH VARIABLE HIGH POWER AMPLIFIERS |
| 摘要 |
A spacecraft includes a payload subsystem including a plurality of transmit antenna feeds, a digital channelizer, and a power amplification arrangement including a plurality of power amplifiers. The power amplification arrangement has at least one input communicatively coupled with an output of the digital channelizer and at least one output communicatively coupled with at least one of the plurality of transmit antenna feeds. A processor is configured to control the digital channelizer, and to adjust a saturated output power of at least one power amplifier of the plurality of power amplifiers in the power amplification arrangement. |
