Abstract

A radar device including a radar function, a driver configured to control a pass device, and a radar controller. The radar function is configured for generating radar frames in a first mode for generating high isolation frames and in a second mode for generating low isolation frames. The radar function has a supply voltage input and is configured to operate with the supply voltage input at a radar supply voltage level. The radar controller configures the driver for controlling the pass device to regulate voltage provided to the supply voltage input of the radar function at the radar supply voltage level with high power supply rejection ratio to minimize ripple voltage when the radar function is in the first mode, and configures the driver to force the pass device into a bypass mode to reduce power dissipation when the radar function is in the second mode.
