Publication number: 20210149018Abstract: One illustrative embodiment of a radar system includes: a signal generator, a variable phase shifter element, and a mixer. The signal generator supplies a frequency modulated continuous wave (FMCW) signal to a transmit antenna protected by a housing, which causes a housing reflection having a frequency offset from the FMCW signal. The variable phase shifter element derives a reference signal from the FMCW signal by applying a time-dependent phase shift based on the frequency offset. The mixer obtains a receive signal including said housing reflection and multiplies the receive signal with the reference signal to produce a downconverted signal.Type: ApplicationFiled: November 18, 2019Publication date: May 20, 2021Applicant: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Danny ELAD, Oded KATZ

Patent number: 9960473Abstract: A system comprises a differential phase shifter based on a differential coupled line coupler that can include a ground metal layer, a bottom metal layer and a top metal layer. The differential line coupler can include differential input lines comprising two metal stack layers (top and bottom), which are arranged diagonally, and the differential output lines are arranged in a complementary diagonal configuration. This layout configuration overcomes the asymmetry caused by the difference in metal layer thickness and width difference, as well as a periphery effect such as the distance to a ground plane or substrate. The proposed diagonal layout configuration balances the characteristic impedance and phase accumulation on each coupled wire of the differential coupled line coupler, which improves the performance of the phase shifter, e.g. lower insertion loss and wider phase tuning range.Type: GrantFiled: November 26, 2015Date of Patent: May 1, 2018Assignee: International Business Machines CorporationInventors: Oded Katz, Nadav Mazor
