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 20240097716 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 an LB/HB mixer to share a single LO signal without extending the original LB LO signal bandwidth.
- Dual-band gain stage implemented to support LB/LB, LB/MB, LB/HB, and MB/HB carrier aggregation.
- LB/HB mixer shares 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 LB LO signal bandwidth.
Potential Applications
The technology can be applied in the development of advanced transceiver systems for mobile communication devices, IoT devices, and other wireless communication systems requiring carrier aggregation support.
Problems Solved
1. Excessive area consumption on the transceiver due to implementing four separate radio frequency mixer chains. 2. Excessive power consumption on the transceiver resulting from implementing multiple mixer chains.
Benefits
1. Reduced space and power consumption on the transceiver. 2. Maintains support for various carrier aggregation combinations. 3. Improved efficiency in handling LB/HB frequency ranges.
Potential Commercial Applications
Optimizing transceiver designs for 5G networks, IoT devices, and other wireless communication systems to enhance performance and efficiency.
Possible Prior Art
Prior art may include patents or publications related to optimizing transceiver designs for carrier aggregation support while minimizing area and power consumption. Research on dual-band gain stages and mixer chain configurations in transceiver systems may also be relevant.
Unanswered Questions
How does the dual-band gain stage impact the overall performance of the transceiver system?
The dual-band gain stage may introduce additional complexity to the transceiver design, potentially affecting factors such as noise figure, linearity, and overall signal quality. Further testing and analysis are needed to determine the impact on performance metrics.
What are the potential challenges in implementing the dual-band gain stage in practical transceiver systems?
Integrating the dual-band gain stage into existing transceiver architectures may pose challenges in terms of design complexity, compatibility with other components, and manufacturing considerations. Addressing these challenges effectively is crucial for successful implementation of the technology.
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.
