Patent ID: 11879966
Assignee: INFINEON TECHNOLOGIES AG
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A radar system, comprising:
a first semiconductor die, comprising:
an oscillator configured to generate a first local oscillator signal; and
a transmitter configured to wirelessly transmit a radar signal based on the first local oscillator signal and wirelessly transmit a wireless signal comprising information corresponding to the first local oscillator signal; and

a second semiconductor die, comprising:
a receiver configured to receive the wireless signal and a reflected radar signal corresponding to a reflection of the radar signal,
wherein the receiver is configured to generate a second local oscillator signal from the information corresponding to the first local oscillator signal of the wireless signal, and
wherein the receiver comprises a mixer configured to receive 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 based on a mixing of the second local oscillator signal and the reflected radar signal,

wherein the first semiconductor die and the second semiconductor die are separated by a distance of at least 5 cm.
