1. A method for operating a radar chip, comprising:
selectively coupling digital phase modulators in the radar chip to corresponding amplifiers in an array of amplifiers in the radar chip, wherein a given phase rotator of phase rotators in the radar chip is coupled to the digital phase modulators, and wherein a given amplifier in the array of amplifiers is coupled to a corresponding antenna output; and
using the phase rotators and the digital phase modulators, synthesizing individual transmit signals for the antenna outputs.
