Multi-band Transceiver with Integrated Couplers for Base Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current base station systems require multiple single-band transceivers for each frequency band, leading to increased material and mounting costs, and external multi-frequency combiners cause signal loss, reducing coverage performance.
Innovation Solution
A multi-band multi-path receiving and transmitting device that includes a broadband antenna, multi-frequency couplers, and a multi-band transceiver, where the multi-frequency couplers are either external or built-in, reducing the number of transceivers and jumpers, thereby decreasing costs and signal loss while improving coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple single-band transceivers are used for each frequency band, then the base station can support multiple frequency bands, but the material cost and mounting cost increase
Solution Approach 1:
The patent implements multi-functionality by enabling a single transceiver to handle multiple frequency bands through multi-frequency couplers. The couplers allow the transceiver to selectively couple with different frequency bands (e.g., Band 1, Band 2, Band 3), making one transceiver perform the work of multiple single-band transceivers. This directly reduces device complexity while maintaining frequency band support capability.
Solution Approach 2:
The patent merges multiple single-band transceiver functions into a single multi-band transceiver by introducing multi-frequency couplers. Instead of having separate transceivers for each frequency band, the couplers combine the frequency band selection and signal routing functions, allowing multiple frequency bands to be handled by one integrated transceiver unit.
2Adaptability or versatility
If external multi-frequency combiners are used to share antenna and feeder, then multi-band receiving is enabled, but signal loss increases and coverage performance deteriorates
Solution Approach 1:
The patent extracts the frequency selection and coupling functionality from external multi-frequency combiners and integrates it directly into the transceiver through built-in multi-frequency couplers. This eliminates the need for external combiners and their associated jumpers, thereby removing the source of signal loss while preserving multi-band receiving capability.
Solution Approach 2:
The multi-frequency coupler acts as an intermediary component that directly connects the antenna to the transceiver's receiving branches, eliminating the need for external combiners and jumpers. This direct coupling path minimizes signal loss while still enabling frequency band selection and multi-band receiving functionality.
3Adaptability or versatility
If external multi-frequency combiners and jumpers are used, then multi-band signal routing is achieved, but material cost and mounting cost increase
Solution Approach 1:
The patent merges the signal routing functionality previously performed by external multi-frequency combiners and jumpers into integrated multi-frequency couplers built into the transceiver. This consolidation eliminates multiple external components and their interconnections, reducing both material cost and mounting complexity while maintaining full signal routing capability for multiple frequency bands.
Solution Approach 2:
The integrated multi-frequency couplers provide universal signal routing capability for multiple frequency bands within a single component, replacing the need for separate external combiners and jumpers. This multi-functional design reduces the total number of components required while maintaining the ability to route signals across different frequency bands.
