Embodiment Construction

[0031] In the ensuing description, one or more specific details are illustrated in order to provide an in-depth understanding of examples of embodiments of the specification. Embodiments may be obtained without one or more of the specific details or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail, so that certain aspects of the embodiments would be apparent.

[0032] References to "an embodiment" or "one embodiment" in the framework of this specification are intended to indicate that a particular configuration, structure or characteristic described with respect to the embodiment is included in at least one embodiment. Thus, phrases such as "in an embodiment" or "in one embodiment," which may be present at one or more points in this specification, do not necessarily refer to the same embodiment. Furthermore, particular configurations, structures or characteristics may be co...

Abstract

A radio frequency transceiver device includes a transmission circuit that generates a transmission signal at a transmission pad connected to a transmission antenna by modulating a radio frequency signal according to a control signal. The first receiving circuit and the second receiving circuit receive the first signal and the second signal at the first receiving pad and the second receiving pad connected to the first receiving antenna and the second receiving antenna. The received first and second signals are demodulated via a radio frequency signal to generate a first demodulated received signal and a second demodulated received signal. The control circuit operates during the reception test phase to generate only control signals to test whether the received first signal corresponds to the received second signal based on the first demodulated received signal and the second demodulated received signal. A reception error signal indicative of a reception error is generated when the test indicates that the received first received signal does not correspond to the second received signal.

Description

[0001] priority statement [0002] This application claims priority to Italian Patent Application No. 102018000004974, filed April 30, 2018, the contents of which are hereby incorporated by reference in their entirety to the fullest extent permitted by law. technical field [0003] This description relates to radio frequency transceiver devices (eg, integrated circuit chips), which can be used in different application fields, eg, for radar systems, eg, for automotive scenarios towards autonomous driving. [0004] One or more embodiments may be applied to integrated circuits (ICs) for ultra-wideband (UWB) radar, frequency modulated continuous wave (FMCW) radar, and / or other radar systems (eg, for automotive and consumer applications). Background technique [0005] Radar systems are used in a wide variety of applications. For example, a radar system may be used to detect obstacles in front of the vehicle, for example, to automatically activate the vehicle's brakes or maintai...
