Abstract: A radar device may include a digital to analog converter (DAC) stage. The DAC stage may generate a plurality of analog signals. The DAC stage may generate a different analog signal for each transmitter chain of a plurality of transmitter chains. Each analog signal of the plurality of analog signals may represent a single digital signal. Each transmitter chain of the plurality of transmitter chains may include a transmit chain portion and switched analog beamforming network (BFN). The transmit chain portion may generate a plurality of intermediate analog signals representative of the corresponding analog signal. The switched analog BFN may generate a plurality of analog transmit signals for an intermediate analog signal of the plurality of intermediate analog signals. The plurality of analog transmit signals may include a beam formed in accordance with a state of the switched analog BFN.
