DIGITAL-TO-ANALOG CONVERTER WITH HYBRID COUPLER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240348258 titled 'DIGITAL-TO-ANALOG CONVERTER WITH HYBRID COUPLER
The current disclosure pertains to a digital-to-analog converter (DAC) with a hybrid coupler for generating quadrature analog signals. The DAC includes an array of unit power amplifiers (cells) that are divided into two portions, one for in-phase components and the other for quadrature components of digital signals. The cells generate corresponding analog signals, which are then combined by the hybrid coupler to produce the final output.
- The DAC features a hybrid coupler that combines in-phase and quadrature components of analog signals with a similar phase.
- The DAC includes an array of unit power amplifiers (cells) that generate in-phase and quadrature components of analog signals.
- The cells are divided into two portions, one coupled to a first column decoder for in-phase components and the other to a second column decoder for quadrature components.
- The hybrid coupler delays the quadrature components by a phase delay (e.g., 90 degrees) before outputting the combined analog signals.
Potential Applications: - Communication systems - Radar systems - Satellite communication - Wireless transceivers
Problems Solved: - Efficient generation of quadrature analog signals - Precise combination of in-phase and quadrature components - Simplified design of digital-to-analog converters
Benefits: - Improved signal accuracy - Enhanced performance in communication systems - Reduced complexity in signal processing
Commercial Applications: Title: "Advanced Digital-to-Analog Converter for Communication Systems" This technology can be utilized in various commercial applications such as: - Telecommunication equipment - Satellite communication systems - Radar systems - Wireless transceivers
Questions about the technology: 1. How does the hybrid coupler enhance the performance of the DAC?
The hybrid coupler combines in-phase and quadrature components of analog signals with a similar phase, improving signal accuracy.
2. What are the key advantages of using an array of unit power amplifiers in the DAC?

Original Abstract Submitted
the current disclosure is related to a column and line digital-to-analog converter (dac) with a hybrid coupler for generating quadrature analog signals. the dac may include an array of unit power amplifiers (cells). a first portion of the cells of the array may be coupled to a first column decoder to receive in-phase components of digital signals and a second portion of the cells may be coupled to a second column decoder to receive quadrature components of the digital signals. the first portion of the cells of the array may generate in-phase components of analog signals and the second portion of the cells of the array may generate quadrature components of the analog signals. a hybrid coupler of the dac may receive the in-phase and quadrature components of the analog signals with a similar phase, delay the quadrature components by a phase delay (e.g., 90 degrees), and output the resulting analog signals.
