Assignee: INFINEON TECHNOLOGIES AG
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 8:
9. A method, comprising:
generating, by an oscillator of a first semiconductor die, a first local oscillator signal;
transmitting wirelessly, by the first semiconductor die, a wireless signal comprising information corresponding to the first local oscillator signal;
transmitting wirelessly, by the first semiconductor die, a radar signal based on the first local oscillator signal, wherein the radar signal and the wireless signal are transmitted simultaneously;
receiving, by a second semiconductor die, the wireless signal and a reflected radar signal corresponding to a reflection of the radar signal;
generating, by the second semiconductor die, a second local oscillator signal from the information corresponding to the first local oscillator signal of the wireless signal; and
mixing, by a mixer of the second semiconductor die, the reflected radar signal and the second local oscillator signal to obtain information on a frequency difference between the reflected radar signal and the second local oscillator signal,
wherein the first semiconductor die and the second semiconductor die are arranged with a distance of more than 5 cm therebetween.
