  • TRANSMITTER HARDWARE SHARING
    Publication number: 20240106466
    Abstract: Methods and apparatus for transmitting wireless signals using multiple transmit chains that share hardware components to reduce transmitter circuit area. One example transmitter circuit for wireless communications generally includes a first transmit chain and a second transmit chain. The first transmit chain and the second transmit chain share a digital-to-analog converter (DAC). For certain aspects, the first transmit chain and the second transmit chain may also share a frequency synthesizer and/or a baseband processor.
