INPUT DRIVE CONTROL FOR SWITCHER REGULATED POWER AMPLIFIER MODULES |
摘要 |
Various embodiments described herein relate to a power management block and an amplification block used in the transmitter of a communication subsystem. Th e power management block provides improved control for the gain control signal provided to a pre-amplifier and the supply voltage provided to a power amplifier which are both in the amplification block. The power expended by t he power amplifier is optimized by employing a continuous control method in whi ch one or more feedback loops are employed to take into account various characteristics of the transmitter components and control values.
