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 20240097715 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 transceivers for mobile communication devices, IoT devices, and other wireless communication systems.
Problems Solved
1. Excessive area consumption on a transceiver due to implementing four separate radio frequency mixer chains. 2. Excessive transceiver power consumption resulting from implementing four separate mixer chains.
Benefits
1. Reduced space and power consumption on the transceiver. 2. Support for multiple carrier aggregation scenarios without compromising performance.
Potential Commercial Applications
Optimizing transceiver design for 5G networks, improving efficiency in IoT devices, enhancing performance in wireless communication systems.
Possible Prior Art
There may be prior art related to optimizing transceiver design for carrier aggregation in wireless communication systems, but specific examples are not provided in the abstract.

What are the potential challenges or limitations of implementing a dual-band gain stage in a transceiver for supporting carrier aggregation?
The abstract does not address any potential challenges or limitations that may arise from implementing a dual-band gain stage. Understanding the drawbacks or constraints of this technology would be crucial for evaluating its practicality and feasibility in real-world applications.
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.
