Method for demodulating a RF signal

An apparatus for demodulating a radio frequency (RF) signal, comprising:

• an RF circuit configured to:
• detect if an analog to digital converter (ADC) of a Near Zero Intermediate Frequency (NZIF) receiver is in a clipping state;
• and
• when the ADC is in the clipping state:
• determine and store a first value representative of a first energy of a received signal demodulated by the NZIF receiver using a first intermediate frequency;
• determine and store a second value representative of a second energy of the received signal demodulated by the NZIF receiver using a second intermediate frequency corresponding to an opposite value of the first intermediate frequency;
• and
• select, from the first intermediate frequency and the second intermediate frequency, an intermediate frequency corresponding to a lowest value of the first value and the second value.

• amplify the RF signal;
• and
• split the amplified RF signal into a first path signal for a first path and a second path signal for a second path.
