Systems for multi-band radar based sensing

Abstract:

Devices, systems, and methods for multi-band radar sensing are disclosed. In an embodiment, an integrated circuit device includes transmit components and receive components, a low-band transmit interface connected to output a first signal at a low-band frequency, a high-band transmit interface connected to output a second signal at a high-band frequency, a low-band receive interface connected to receive a third signal at the low-band frequency, a high-band receive interface connected to receive a fourth signal at the high-band frequency, and mixers connected to upconvert the first signal at the low-band frequency to the second signal at the high-band frequency for transmission from the high-band transmit interface and to downconvert the fourth signal at the high-band frequency received at the high-band receive interface to a fifth signal at the low-band frequency, wherein the upconversion and the downconversion are implemented using a conversion signal at a conversion frequency.
