Abstract: 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.
