DIGITAL-TO-ANALOG CONVERTER WITH HYBRID COUPLER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18755317 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 in-phase and quadrature components of analog signals, which are then processed by the hybrid coupler to output the resulting analog signals.
- Array of unit power amplifiers (cells) in the DAC
- Cells divided into two portions for in-phase and quadrature components of digital signals
- Hybrid coupler processes in-phase and quadrature components of analog signals
- Coupler delays quadrature components by a phase delay (e.g., 90 degrees)
- Output of resulting analog signals after processing by the hybrid coupler
Potential Applications: - Communication systems - Radar systems - Signal processing applications
Problems Solved: - Efficient generation of quadrature analog signals - Precise processing of in-phase and quadrature components
Benefits: - Improved signal accuracy - Enhanced performance in communication and radar systems
Commercial Applications: Title: "Advanced DAC with Hybrid Coupler for Signal Processing Applications" This technology can be utilized in various commercial applications such as telecommunications, radar systems, and signal processing equipment. The precise generation and processing of quadrature analog signals can significantly enhance the performance of these systems, leading to improved efficiency and accuracy.
Questions about the technology: 1. How does the hybrid coupler in the DAC improve the generation of quadrature analog signals? The hybrid coupler receives in-phase and quadrature components of analog signals, delays the quadrature components, and outputs the resulting analog signals with enhanced accuracy. 2. What are the potential commercial applications of this DAC technology? This DAC technology can be applied in communication systems, radar systems, and various signal processing applications to improve signal accuracy and performance.
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.
