Abstract: Mismatch detection using periodic structures is provided. Embodiments described herein can measure and detect mismatch between two loads in a radio frequency (RF) system without the need for external calibration by referencing their measurements into a small set of parameters that are intrinsic to the RF system design. This approach can be used to compare impedances of two loads and measure their impedances relative to each other without requiring any external calibration (e.g., the approach does not assume any prior known physical quantities in the system, such as a reference impedance). This approach can be used to compare the two loads to each other, as well as to quantify the amount of mismatch between these loads by calculating reflection coefficient between the loads. Loads can be passive devices, such as antennas, or they can be active devices, such as amplifiers.

Abstract: A Frequency Modulated Continuous Wave (FMCW) radar system is provided that includes a chirp profile storage component configured to store a chirp profile for each chirp of a frame of chirps and a timing engine coupled to the chirp profile storage component to receive each chirp profile in transmission order during transmission of the frame of chirps, in which the timing engine uses each chirp profile to configure a corresponding chirp.
