1Productivity
If carrier aggregation is implemented using traditional architecture with external low noise amplifiers and power splitters, then downlink throughput is improved, but device complexity, size, and cost increase
Solution Approach 1:
The patent combines the low noise amplifier and power splitter functions directly into the transceiver integrated circuit, eliminating the need for separate external components. This integration merges multiple functions into a single chip, reducing device complexity while maintaining carrier aggregation capability for improved downlink throughput
Solution Approach 2:
The transceiver circuit is designed with multi-functional capability to perform both low noise amplification and power splitting operations internally. This universal design allows the same circuit to handle multiple functions that traditionally required separate dedicated components, thereby reducing overall device complexity
