Abstract: A radar assembly and a method for operating the radar assembly is disclosed, where a first frequency comb generator is arranged in the transmitting unit between the first oscillator and the transmitting antenna and a second frequency comb generator is arranged in the receiving unit between the second oscillator and the first mixer. On the transmitter side a first frequency comb generator is controlled with the first oscillator frequency in order to generate a primary signal containing a plurality of frequency components, on the receiver side a second frequency comb generator is controlled with a second oscillator frequency in order to generate an output signal containing a plurality of frequency components, the output signal generated in such a way is mixed with a third oscillator frequency, and the intermediate frequency is generated by mixing the received reflected signal with the mixed signal.

Abstract: Disclosed herein are systems, methods, and devices for determining a position of an object using a passive transponder and a flying object (such as a satellite, drone, etc.). The passive transponder may be attached to an object to be located (such as a small animal, a bird, a good/product, etc.) and includes one or more antennas and a modulator configured to modulate a backscattering coefficient of the one or more antennas. The one or more antennas are configured to reflect at least a portion of a flying object signal transmitted from the flying object in response to the modulated backscattering coefficient in order to determine a position of the passive transponder using the reflected flying object signal.

Abstract: A system and method for testing devices such as integrated circuits (IC) with integrated antenna arrays configured for wireless signal reception. The method performs a calibration operation on a reference device under test (DUT). During the calibration operation, the DUT receives a series of first signals from a first far-field (FF) location and a series of array transmissions from a second near-field (NF) location using different beamforming settings, and determines therefrom a set of calibration parameters. The calibration parameters may be used by a probe antenna system (PAS) to transmit an array transmission to the DUT from the second NF location to emulate a single probe or multi-probe transmission from the first FF location.

Abstract: In a multi-chip module and method, the multi-chip module includes a carrier; a multimode optical waveguide formed on and/or in the carrier; a first and second chip disposed on the carrier and coupled to the multimode optical waveguide; wherein the first chip is configured to transmit light beams into the multimode optical waveguide; the multimode optical waveguide is configured to generate mixed light beams that are an at least partial superposition of the light beams; the second chip is configured to receive the mixed light beams from the multimode optical waveguide; and the second chip is configured to store a representation of the received mixed light beams as a transmission signature and/or as a cryptographic key in a memory associated with the second chip, and/or compare the representation of the received mixed light beams with a target representation stored in the memory associated with the second chip.

Abstract: A system and method for testing (e.g., rapidly and inexpensively) devices such as integrated circuits (IC) with integrated antennas configured for millimeter wave transmission and/or reception. The method may first perform a calibration operation on a reference device under test (DUT). The calibration operation may determine a set of reference DUT FF base functions and may also generate a set of calibration coefficients. After the calibration step using the reference DUT, the resulting reference DUT FF base functions and the calibration coefficients (or reconstruction matrix) may be used in determining far-field patterns of DUTs based on other field measurements, e.g., measurements taken in the near field of the DUT.
