Abstract
An automotive radar system that is switchable between one or more high power modes and one or more increased channel modes. The radar system includes multiple transmit antennas, an integrated circuit including a transmit chain generating a positive transmit signal and a negative transmit signal that together form a differential transmit signal, and a coupling interface. The coupling interface configurably couples the differential transmit signal to two transmit antennas of the multiple transmit antennas to selectively drive the two transmit antennas in either a differential mode or in a power-combining mode that combines power from the positive transmit signal and negative transmit signal to drive a first transmit antenna of the multiple transmit antennas while isolating a second transmit antenna of the two transmit antennas.
