Abstract
An array of antennas includes transmitter and receiver circuits. The transmitter includes a digital-to-analog converter (DAC), splitter and filter circuits, mixer circuits, and antennas. The DAC circuit converts a digital signal into an analog signal. The splitter and filter circuits separate frequencies of the analog signal into split signals. The mixer circuits multiply frequencies from the split signals by different frequencies of carrier signals to generate modulated signals that are converted by the antennas into radio frequency (RF) signals. The receiver includes antennas, mixer circuits, a summing circuit, and an analog-to-digital converter (ADC). The antennas in the receiver receive RF signals that are converted into electrical signals. The mixer circuits multiply frequencies from the electrical signals with different frequencies of carrier signals. The outputs of the mixer circuits are summed by the summing circuit to generate a summed signal that is converted to digital by the ADC.
