Methods for multi-band radar based sensing

Abstract:

Devices, systems, and methods for multi-band radar sensing are disclosed. A method for operating an IC device involves setting a configuration of the IC device to select from available options of low-band and high-band operational modes, transmitting and receiving RF signals at a low-band frequency when the configuration of the IC device is set to the low-band operational mode, and transmitting and receiving RF signals at a high-band frequency when the configuration of the IC device is set to the high-band operational mode, wherein transmitting RF signals at the high-band frequency comprises upconverting a first signal at the low-band frequency to a second signal at the high-band frequency and wherein receiving RF signals at the high-band frequency comprises downconverting a third signal at the high-band frequency to a fourth signal at the low-band frequency, wherein the upconversion and the downconversion are implemented using a conversion signal at a conversion frequency.
