CONTROLLING A POWER AMPLIFIER BASED ON TRANSMITTER OUTPUT EMISSIONS |
摘要 |
<p>Methods and systems for controlling the supply voltage provided to a power amplifier (PA) in a radio frequency (RF) transmitter based on measured output spectrum emissions are provided. In an embodiment, the PA supply voltage is adjusted such that spectrum emission limits are satisfied with predetermined margins. In another embodiment, the predetermined margins are reduced to lower power consumption of the PA.</p> |
