Abstract:
A device and method for calibrating a wideband radio frequency receive chain are disclosed. In one aspect, the device includes a wideband radio frequency receive chain and a processing module configured to perform a spectral analysis. The receive chain includes an input block and a radio frequency processing assembly. The device is configured to implement a first calibration phase of the input block and a second calibration phase of the receive chain.

Claim (Index 1):
A method of calibrating the power of a wideband radio frequency receive chain configured to receive an input radio frequency signal from a receiving antenna, in a frequency band, the method implemented in a calibration device comprising the wideband radio frequency receive chain and a spectral analyzer, the receive chain including an input block connected at the input of a radio frequency processing assembly, the method comprising:\n a first calibration phase of the input block, comprising, for at least one temperature value of the input block and a frequency, generating a given power spectral density of noise, using a noise source configured to be selected and controlled from the input block, and computing and storing at least one equivalent power spectral density of noise returned at the input of the input block; and a second calibration phase of the power gain of the receive chain, comprising:\n generating a given power spectral density of noise, \n measuring a power spectral density of noise at the output of the receive chain, and \n computing a power gain of the receive chain as a function of the power spectral density of noise at the output of the receive chain and the equivalent power spectral density of noise returned at the input corresponding to the given power spectral density of noise generated in the generating.
