ELECTRONIC DEVICE AND WIRELESS COMMUNICATION SYSTEM THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17984950 titled 'ELECTRONIC DEVICE AND WIRELESS COMMUNICATION SYSTEM THEREOF
Simplified Explanation
The abstract describes an electronic device that includes a network monitor, a transceiver, a transmission module, and an envelope tracking modulator. The device is designed to optimize the performance of a power amplifier based on network environment information.
- The electronic device has a network monitor that collects information about the network environment related to a radio frequency transmission signal.
- A transceiver generates an envelope signal of the RF transmission signal.
- A transmission module includes a power amplifier that receives the RF transmission signal from the transceiver and amplifies it.
- An envelope tracking modulator receives the envelope signal from the transceiver and adjusts the bias of the power amplifier to match the envelope signal.
- The ET modulator determines the magnitude of the bias of the power amplifier based on the network environment information acquired by the network monitor.
Potential applications of this technology:
- Wireless communication devices such as smartphones, tablets, and laptops could benefit from improved power amplifier performance.
- Internet of Things (IoT) devices that rely on RF transmission signals could have better signal quality and efficiency.
- Telecommunication infrastructure equipment like base stations and routers could optimize their RF transmission signals based on network conditions.
Problems solved by this technology:
- Power amplifiers in electronic devices often operate at a fixed bias, which may not be optimal for different network environments.
- Inefficient power amplifier operation can lead to wasted energy, reduced battery life, and poor signal quality.
- By adjusting the bias of the power amplifier based on network environment information, this technology aims to improve overall performance and efficiency.
Benefits of this technology:
- Improved power amplifier performance can lead to better signal quality, longer battery life, and enhanced data transmission speeds.
- Optimizing the bias of the power amplifier based on network conditions can result in more efficient use of power, reducing energy consumption.
- The ability to dynamically adjust the power amplifier bias can adapt to changing network environments, ensuring optimal performance in various conditions.
Original Abstract Submitted
An electronic device includes a network monitor configured to acquire network environment information related to a radio frequency (RF) transmission signal; a transceiver configured to generate an envelope signal of the RF transmission signal; a transmission (Tx) module including a power amplifier for receiving the RF transmission signal from the transceiver and amplifying the RF transmission signal; and an envelope tracking (ET) modulator configured to receive the envelope signal from the transceiver and to provide a bias of a power amplifier to correspond to the envelope signal, wherein the ET modulator determines a magnitude of the bias of the power amplifier based on the network environment information acquired by the network monitor.
