Abstract
A radiofrequency transmission/reception integrated circuit includes at least one radiofrequency signal amplifier (PA, LNA), the at least one amplifier being configured, in operational mode, so as to perform a function of amplifying a radiofrequency signal applied at input, wherein the amplifier is configured so as to perform an oscillator function in a self-test mode of the integrated circuit, to generate a radiofrequency signal on at least one of the input or the output of said amplifier. A self-test method for such an integrated circuit is also provided.
Claims18
A radiofrequency transmission and/or reception integrated circuit comprising at least one radiofrequency signal amplifier, said at least one amplifier being configured, in operational mode, so as to perform a function of amplifying a radiofrequency signal applied at input, said amplifier being configured so as to perform an oscillator function in a self-test mode of the integrated circuit, to generate a radiofrequency signal (SinRF) on at least one of the input or the output of said amplifier, wherein the integrated circuit is configured, in said self-test mode, so as to allow said radiofrequency signal to propagate in at least one component of said radiofrequency integrated circuit, separate from said amplifier, and in that it also comprises a measuring circuit (DETA) for measuring a signal generated following propagation of said radiofrequency signal in said component of said integrated circuit and representative of at least one characteristic of said component.
