Multichannel Transceiver for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals require multiple transceivers for different communication modes and frequency bands, leading to increased cost and size due to the need for separate transceivers for 5G/4G/3G/2G and WIFI/BT communications.
Innovation Solution
A mobile terminal with a multichannel transceiver that includes a central processing unit, multiple power amplifiers, transmitter and receiver modules, low noise amplifiers, and a switch module, allowing for simultaneous support of multiple communication modes and frequency bands using a single transceiver, with each module capable of filtering, frequency-converting, and amplifying RF signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate transceivers are used for different communication modes (5G/4G/3G/2G and WIFI/BT), then communication reliability is improved, but device cost and size increase
Solution Approach 1:
The patent combines multiple separate transceivers (5G/4G/3G/2G transceiver and WIFI/BT transceiver) into a single integrated multichannel transceiver. This merging approach maintains the reliability of separate transceivers while reducing device cost and size by sharing common components such as power amplifiers, low noise amplifiers, filters, and control units across multiple communication modes.
Solution Approach 2:
The multichannel transceiver is designed with universal functionality to support multiple communication modes (5G/4G/3G/2G and WIFI/BT) simultaneously. The device can dynamically switch between different communication protocols and frequency bands using a single transceiver unit, eliminating the need for dedicated transceivers for each mode while maintaining communication reliability.
2Device complexity
If a single multichannel transceiver is used for multiple communication modes, then device cost and size are reduced, but signal interference and clutter increase
Solution Approach 1:
The multichannel transceiver internally segments different communication channels (5G/4G/3G/2G and WIFI/BT) into separate processing paths with dedicated transmitter and receiver modules for each mode. This segmentation allows independent signal processing for each communication type, reducing mutual interference while maintaining the benefits of a unified transceiver structure.
Solution Approach 2:
The patent introduces switch modules and filter banks as intermediary components between different communication channels. These intermediaries selectively route signals for different communication modes and filter out unwanted frequencies, effectively isolating channels and reducing clutter interference while allowing the single transceiver to handle multiple modes efficiently.

AI summary
A mobile terminal and a system with a multichannel transceiver are provided. The mobile terminal includes a central processing unit and a multichannel transceiver. The central processing unit outputs first and second transmitted signals to a first transmitter module and a second transmitter module. The first and second transmitted signals are filtered, frequency-converted, amplified, and transmitted to corresponding transmitting channels. First and second received signals received by a plurality of receiving channels are amplified and then transmitted to a first receiver module and a second receiver module, respectively, and the first and second received signals are frequency-converted, filtered, and output to the central processing unit.
