Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in achieving high power and small volume simultaneously due to high heat consumption and volume requirements, particularly in scenarios with strict temperature and space constraints.
Innovation Solution
The signal transceiving device is connected to a signal amplification device through cables, removing power amplifiers and low noise amplifiers from the transceiving device, ensuring synchronization through control instructions and direct current bias voltages, and allowing the amplifiers to be placed remotely, reducing heat and volume.

Engineering Contradiction Analysis
1Reliability
If power amplifiers and low noise amplifiers are integrated into the signal transceiving device, then signal transmission and reception functions are complete, but heat consumption increases and device volume increases
Solution Approach 1:
The patent divides the signal transceiving system into two separate devices: a signal transceiving device and a signal amplification device. The power amplifier and low noise amplifier are extracted and placed in the signal amplification device, which is connected via cables. This segmentation allows the transceiving device to have reduced heat consumption and volume while maintaining complete signal transmission and reception functions through the distributed architecture.
2Reliability
If power amplifiers and low noise amplifiers are integrated into the signal transceiving device, then signal transmission and reception functions are complete, but device volume increases
Solution Approach 1:
The patent extracts the power amplifier and low noise amplifier from the signal transceiving device and places them in a separate signal amplification device. This extraction reduces the volume of the transceiving device while maintaining signal transmission and reception functions through the connected amplification device, which is positioned remotely and connected via cables.
3Use of energy by moving object
If amplifiers are placed remotely and connected through cables, then heat consumption and volume are reduced, but synchronization between devices becomes more difficult
Solution Approach 1:
The patent implements preliminary synchronization by having the signal transceiving device send a first synchronization signal to the signal amplification device before transmitting the first radio frequency signal. The amplification device uses this synchronization signal to pre-configure its amplifiers, ensuring they are ready to process the incoming signal at the correct time. This preliminary action maintains synchronization despite the remote placement and cable connections.
