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 17946739 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 without extending the original LB LO signal bandwidth.
- The dual-band gain stage reduces space and power consumed on the transceiver.
- It maintains support for LB/LB, LB/MB, LB/HB, and MB/HB carrier aggregation.
Potential Applications
The technology could be applied in mobile devices, IoT devices, and other wireless communication systems requiring carrier aggregation support while minimizing power consumption.
Problems Solved
1. Excessive area consumption on a transceiver due to implementing four separate mixer chains for carrier aggregation. 2. Excessive power consumption on the transceiver when using multiple mixer chains.
Benefits
1. Reduced space and power consumption on the transceiver. 2. Improved efficiency in supporting various carrier aggregation combinations.
Potential Commercial Applications
Optimizing transceiver design for 5G devices Enhancing performance in multi-band communication systems
Possible Prior Art
There may be prior art related to optimizing transceiver design for carrier aggregation support, but specific examples are not provided in this context.
Unanswered Questions
How does the dual-band gain stage impact the overall cost of manufacturing the transceiver?
The cost implications of implementing the dual-band gain stage are not addressed in the abstract. It would be beneficial to understand if the technology leads to cost savings or increased production costs.
Are there any limitations to the dual-band gain stage in terms of frequency range or compatibility with different wireless standards?
The abstract does not mention any potential limitations of the dual-band gain stage. Exploring the technology's compatibility with various frequency ranges and wireless standards could provide valuable insights into its practical 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.
