WIRELESS COMMUNICATIONS SYSTEM, POWER SUPPLY SYSTEM, AND TERMINAL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17789011 titled 'WIRELESS COMMUNICATIONS SYSTEM, POWER SUPPLY SYSTEM, AND TERMINAL DEVICE
Simplified Explanation
The patent application describes a power supply circuit in a wireless communications system that includes an envelope tracking modulator connected to two power amplifier circuits. The power supply circuit supplies power to the first power amplifier circuit when the transmit signal output by a processor is within a specific bandwidth range, and supplies power to the second power amplifier circuit when the transmit signal meets a different bandwidth range.
- The power supply circuit in a wireless communications system includes an envelope tracking modulator.
- The envelope tracking modulator is connected to a first power amplifier circuit and a second power amplifier circuit.
- The power supply circuit supplies power to the first power amplifier circuit when the transmit signal is within a first bandwidth range.
- The first power amplifier circuit amplifies the power of the transmit signal.
- The power supply circuit supplies power to the second power amplifier circuit when the transmit signal meets a second bandwidth range.
- The second power amplifier circuit amplifies the transmit signal.

Original Abstract Submitted
A power supply circuit in a wireless communications system includes an envelope tracking modulator coupled to a first power amplifier circuit and a second power amplifier circuit, so that the power supply circuit supplies power to the first power amplifier circuit and the second power amplifier circuit. When a transmit signal output by a processor is within a first bandwidth range, the power supply circuit supplies power to the first power amplifier circuit, and the first power amplifier circuit amplifies power of the transmit signal. When the transmit signal output by the processor meets a second bandwidth range, the power supply circuit supplies power to the second power amplifier circuit, and the second power amplifier circuit amplifies the transmit signal.
