DUAL-BAND RF MIXER CHAIN USING DUAL-BAND MATCHING NETWORK AND SHARED LOCAL OSCILLATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17946683 titled 'DUAL-BAND RF MIXER CHAIN USING DUAL-BAND MATCHING NETWORK AND SHARED LOCAL OSCILLATOR
Simplified Explanation
The patent application aims to support carrier aggregation while reducing area and power consumption on a transceiver by implementing a dual-band gain stage that allows LB/HB mixers to share a single LO signal.
- Dual-band gain stage implemented to support LB/LB, LB/MB, LB/HB, and MB/HB carrier aggregation.
- LB/HB mixers share a single LO signal to reduce space and power consumption on the transceiver.
- Dual-band matching network provides impedance matching at LB and HB frequencies without extending the original LB LO signal bandwidth.
Potential Applications
The technology can be applied in the development of advanced transceivers for mobile communication devices, IoT devices, and other wireless communication systems requiring carrier aggregation support.
Problems Solved
1. Excessive area consumption on a transceiver due to implementing four separate radio frequency mixer chains. 2. Excessive power consumption on a transceiver resulting from implementing multiple mixer chains.
Benefits
1. Reduced space and power consumption on the transceiver. 2. Improved efficiency in supporting multiple carrier aggregation scenarios. 3. Enhanced performance in dual-band frequency applications.
Potential Commercial Applications
Optimizing transceiver designs for 5G networks, IoT devices, satellite communication systems, and other wireless communication technologies.
Possible Prior Art
Prior art may include patents or publications related to mixer chain designs, carrier aggregation techniques, and impedance matching networks in transceiver systems.
Unanswered Questions
How does the dual-band gain stage impact the overall performance of the transceiver system?
The dual-band gain stage may improve efficiency and reduce power consumption, but the specific performance metrics and trade-offs need to be further analyzed and compared with existing solutions.
What are the potential challenges in implementing the dual-band gain stage in practical transceiver designs?
Challenges such as signal interference, component integration, and manufacturing costs may arise when implementing the dual-band gain stage in real-world transceiver systems. Further research and development are needed to address these challenges effectively.
Original Abstract Submitted
This case is directed to supporting LB/LB, LB/MB, LB/HB and MB/HB carrier aggregation while reducing the area consumed on a transceiver and reducing power consumed on the transceiver. In some cases, four supporting such carrier aggregation may include implementing four separate radio frequency mixer chains. However, implementing four separate mixer chains may consume excessive area on the transceiver and may result in excessive transceiver power consumption. By leveraging the fact that HB LO frequency ranges overlap with LB LO frequency ranges, a dual-band gain stage may be implemented such that an LB/HB mixer may share a single LO signal (e.g., so as to provide a dual-band matching network that may provide impedance matching at LB and HB frequencies) without extending an original LB LO signal bandwidth. The dual-band gain stage may reduce space and power consumed on the transceiver while maintaining support for LB/LB, LB/MB, LB/HB and MB/HB carrier aggregation.
